Alright, got the Z back from the bodyshop.
Verdict is that it had been hit from the front, left side went down, right side went up, all of it shifted to the left some.
They got it all straightened back out, and the body panels line up pretty well now. They'll look even better after some shimming and tweaking. This does show me how bad of shape the hood is in though. It was pretty bad to start with, before it fell over in the gravel, so no big loss b/c of that accident. Good thing I have a spare... no vents for it though, yay.
It still lists a little bit to the left, but they said it's the springs, which I could definitely believe. Coilovers should fix that problem. Hopefully this weekend I'll get most of the bushings installed and take it to be aligned.
So that's $500 knocked out of the budget. This is turning into quite the cluster$@#^ of surprises. Now I just need to swap out the crapped tranny (around $300 ) and replace the dead brake booster and it'll be DD comfy. From there I'll install the bushings, get coilovers, do the bodywork and paint, and then I'll be in my happy place with it for awhile till I can afford megasquirt.
