Need pics of 230/250 engine mounts

[theastronaut]

I'm about to start mocking up the engine and transmission in my '66 and I'm starting from scratch with nothing to go by. I bought it as an unfinished project so I didn't have the privilage of taking it apart myself. It's a bare frame, and I've got a 250 engine block, and a T56 six speed. I've got perches and new motor mounts, but I'm not sure what set of holes to use on the frame rails or crossmember for the perches. It looks like it only goes together one way, but I want to make sure before I make my transmission crossmember for the T56. I was thinking that an inline 6 used the foward set of holes on the frame rails, but the perches I have only line up with the rear set of holes. The guy I bought it from was going to put a V8 in it, so maybe I have V8 perches? Or are they the same as an I6? Any help would be greatly appreciated!
