Cheers, I'll have a look. I'm not sure what the light boxes are like, possibly fixable, and I have one new one somewhere, also from a saloon. Knowing my luck, it'll be the same side.
I've done a bit more scraping around the back end now, to see what the rear corner is like. I was right, there's a bit of filler in it. Well, really, most of it is (was) filler. There's a scabby rusty bit of steel stuck in behind the rear arch, and any attempt at shaping it was done with filler. Same around the rear light aperture, there's plenty on there too.
The rear arch has been welded every couple of inches, so at least it will be easy to remove. It's a good 5mm behind the quarter panel, for no apparent reason. The bottom of the scabby repair should be welded to the spare wheel well, but it isn't. Looks as if the underseal has been put on before the filler.
And, good news, it definitely is a hatch
See, the red stripes are still there, under the filler.
For a change I figured I'd sort out the back panel ready to go on. Those who read the first page know I bought a back panel off eBay with a bit missing, and need to join on a spare top section that I already had. For some reason, the HC estate back panel is made in two pieces, with the top section (the light apertures and boot flange) spot welded to the lower valance section. Saloon and coupe back panels are pressed in a single piece. Unfortunately my spare top section wasn't removed by drilling out spot welds as it should have been, but was cut off above the join. The first step therefore was to weld a ~20mm strip to the bottom edge to allow it to be plug-welded in place. This was done and, after the welds were ground down, a short step joggled into it to match the other side.
When I came to offer it up and measure various parts, it turned out that the distance from the light aperture to the "hump" at the top of the valance was much shorter on the untouched side than it could be on my repaired side, by about 3mm. Turns out I had the same problem (though not as bad) with this back panel as I did with the one on my previous Sportshatch job - the two sections had been spot-welded together in the wrong place. Now, you may be thinking that 3mm on a seventies Vauxhall is no big deal, but if you look at this atrocious photo:
you'll see that in the top one, with the bad back panel, if I line up the pressing so that the light aperture joins the corner of the quarter panel, then the hump at the top of the valance (in the yellow ellipse) doesn't match. This also means that the bottom edge of the valance won't be in the right place to join the inner valance. Compare that to the lower part with a good back panel, where both sections line up correctly.
Only thing for it, then, was to drill out the spot welds and separate the top and bottom half. I've now done that, welded the two upper halves together, and when I've ground the welds down I'll weld the top and bottom together again. This adds further support to the argument that the reason NOS panels are still around is because they're panels that were ordered when the cars were newer, didn't fit properly, and were put on one side and a replacement sourced. Then, for some reason, they've sat around instead of being sent back to the factory.

Lots of panels had to be adjusted / trimmed / fettled - it was a accepted practice in the accident repair trade throughout the 1960's - 1990's - Fettling & final panel fits on new vehicle production lines was also a common practice throughout this period - build qualities on panels started to become much improved as the industry entered the 2000's - Hence its not surprising to find ill fitting new old stock panels - Reproduction panels are another thing entirely and there are a number of companies manufacturing reproduction / repair panels for the classic market - Some are good but there is a good number that are of a very poor fit and require extensive works before they actually fit to any acceptable standard - much to the point as a restorer I find it virtually impossible to estimate times on the fitting of repair panels until I actually undertake the repair itself
We used to find a lot of the old Vauxhall panels werent brilliant, replacement HB Viva front wings are all wrinkly if you look down them which i guess was down to worn tooling
Someone did tell me all the poorly pressed panels were sent out to the dealers to sell on rather than used on production, how true that was I dont know!
After a bit of messing around replacing the rear shock absorber mounting, and some other excuses like it being too cold to work, I've cut the bottom off the rear quarter panel. Because the previous restorer had cut this back above the swage line, I've decided to cut all the swage off, and that can go on from the replacement quarter. Much easier than trying to get it straight if I have a join across it, and maybe have a different profile because of tooling wear and so on.
All the internal structure has surface rust on it, so I've been cleaning that up and applying rust killer to it, then I'll give it a coat of paint. It's not a perfect solution, but so far it's managed 45 years so it ought to keep it going to a similar time again.
And now, offering up the replacement rear quarter.
It doesn't fit properly at the back because it's from a saloon and the back end is a different shape, and it doesn't fit around the door aperture because, well, I don't know why not. But I had that trouble on my other hatch, so I'll just have to make some of that bit to close the gap. Should be able to finish off the inner sill now, though.
Some of that is the camera - it always seems to make things look darker than they are. To the right, just outside the edge of the photo, there is an 8' tube mounted on the wall, a recent addition. I have light at the back of the shed (where the Audi is) but I didn't want to move the Audi to get this done.
Back end of the inner sill was welded in place this afternoon, I think the inner wheelarch edge will be next.
Yes, it is. I keep running through in my head how little there is to do on this side before I can turn it round and attack the other, but struggle to actually make progress, so it's nice to actually do something.
I've spent a few days trying to find out the shape of the sealing panel that sits between the inner and outer sill on these cars, as the one in the car had rusted away. I got a really helpful response from a chap in the Viva Owners Club who happened to have access in to his (they're not easy to see on a complete car), so I made one and covered it in weld-through primer.
I tacked the sill on this afternoon, and only then did I remember that I should have fitted the sealing panel before doing that. Fortunately I only had to grind through a couple more spot welds and I could push it into place from the back.
I think it's to stop draughts getting into the rear quarters on two-door cars. There's a hole in the lower part of the front door pillar to allow rustproofing in, so if the splash shields aren't present, that would let moving air through the sill section and into the back of the car. And of course there are two holes on the bottom edge of a HC front wing that would let stuff in as well.
Can't say I ever noticed that on my Firenza though - for years that had no splash shields fitted. I didn't do the bodywork on it, so I don't know if it has these fitted or not.
Now I'm making the bottom corner of the door pillar, hopefully get that tacked on this afternoon and then back on to removing the remnants of the spare wheel well so I can make and fit that while the bottom of the quarter panel is still off.
I finally fixed the front section of the drivers floorpan in place last weekend, so that's all that corner done now, unless you count a little bit where I cut it too short. Haven't decided yet whether to try to weld a piece in, or just use a slightly larger blob of mastic to close it off.
Yesterday I spent a bit of time making and fitting about 2/3 of the inner wheelarch, another job that needs to be done in order for the rear quarter to fit. This afternoon I spent a bit less time cutting it all off again, as it was holding the quarter a bit low. Grr.
Looks tidy, I keep thinking about getting some of the Australian remanufactured floor pans to keep in stock but they arent cheap by the time shipping/duty etc is added on
I've sold quite a few of my floors. I'd like to get them better, but they go in OK with a bit of pushing. This is the first time I've fitted one myself, though, as I hadn't got the bead roller when I did my last hatch. I was quite relieved that things lined up properly.
I've been doing bits of the inner wheelarch lip now that I think I have the rear quarter in the right place, and I've moved onto the back panel as well as move of that needs to go in before the quarter can go on. I've made the replacement inner back panel:
Last time I did this in one piece, but three sections made it a lot quicker to do. One piece (the one with some weld-through primer on it) is now in place, and I'm finishing off the inner wheelarch. The piece on the left in the photo needs to be fixed to the end of the spare wheel well before it goes in the car as it's easier to weld that way.
Soon I'll need to move the car so I can get to the other side of it. I think I'll swap it with the Audi so I have access all round - I'd left that in place because I intended to switch between the two cars so I got stuff done on both, but I haven't been doing that.
