I need to do some repair on a 240Z front frame rail (its bent inwards towards the engine) from about the strut tower to just behind the T/C mounting bracket. I can get donor parts from a 280Z 2+2 but I'm uncertain whether these would be interchangable.

I don't have my S30 parts CD with me today so if anyone knows the answer, please post it.

I suppose that I could always fabricate what I need, but using good donor parts seems the better way to go.

From the firewall forward all S30 bodies are the same (both coupes and 2+2s) so if you need a donor section from another S30 it will fit. The rail sections from the firewall back is different (similar- 240 and 260, similar- all 280s, 2+2 are just longer at the back sections)
