I've been disassembling my car and getting a better sense of what happened to it before my ownership. I think the car was hit on the left rear corner. It doesn't appear that it crumpled much at all. In fact, the left taillight assembly was re-used (the black plastic on the end is missing a 1 cm piece and there's a crack in the middle of the black plastic on the back). There's also a really bad bondo repair about the diameter of an average hand by the tailight. So I don't think much crumple-type of damage was done. But, that hit must have somehow twisted the chassis by either pushing the left rear down and/or pushing the right rear up. There is a big difference in height left to right when looking at the rear end (like 1 -1.5"). The suspension ear on the right is 4mm higher than the one on the left. The latter might even be within factory spec, no? Also, the distance between the trunk channels on the rear fenders is within spec for the front half, but the back half progressively narrows to being 1.5cm too narrow.
The longs, rockers, firewall and hell hole are shot and the door gaps by the door handles are too big (8-9mm). So, I'm wondering, (aside from the option of scrapping it), do I get the chassis straightened before metal surgery, or after surgery on the main structural parts? I could see the former tearing the car apart, and the latter creating imperfections in the newly repaired work. |

I had a local expert take a look this weekend. Setting aside for the moment his conclusion that this car is "not a candidate for restoration," he did have a good idea for how to fix the twist. The rear suspension points differ at the most 1/4" side to side. The twist is almost entirely before the shock towers. So, his idea is to cut-off the back end of the car before the shock towers and replace with a donor. I've seen pics of repairs up to the trunk crossmember, but would this work with a butt weld straight across all the way coming to just behind the shock tower area?
