That image is super useful, thanks!
Just taken a couple of quick measurements. The twist and bend has put the part of the frame rail from the tension rod mount back about 10mm out of position at its extreme. Everything else - strut towers, rad support, etc - are straight and true.
As I’ve mentioned before, my theory is that at some point, the car ran over something really hard; there is no other damage to the right front area other than a twist that seems to suggest energy was transferred through the tension rod. With it, the twist also put a crease into the lower bulkhead where the chassis rail joins it. Ultimately, that’s not an issue as that section of bulkhead is being cut out for the RHD conversion and the battery tray area adjoined to it will be refabricated due to rust, but I need that frame rail and inner wing to be in the right place before I think about any RHD conversion work on that side.
The other issue here that has me ruminating on the idea of a new rail is that it shows evidence of battery acid-inspired rust. Obviously the inner wing is shot adjacent to it, and the top of the rail has some pitting, although nothing really nasty. However, there’s a couple of small rust holes in that multi-skinned triangular section under the bulkhead, suggesting battery acid got in there. If it can be pulled straight, I doubt the rust is severe enough to really justify anything more than a welding repair to the rust holes, but I don’t know...
Obviously, replacing the chassis rail is a bunch more work. Straightening it would require all the hassle and expense of taking the shell to be pulled - or expense of me getting a body dozer and trying it myself (not something I’m sold on the idea of tackling).
