I have to put the door back on before I can drive it home, but once I do that I'll get some pictures up soon.

I just picked up a 280zxr for hella cheap but it has two problems, I need to replace the door hinges to the driver side and it needs tranny work. Do any other Z cars Tranny blocks match up to the engine of the zxr or do I have to go through a dealer, also I can just tear the hinges off of another old 79 280zx right because the bodies are the same besides the spoiler?
