68 C10 Q:How thick are the Radiator Support Mounts?

[SWINGSAX68]

I really need to know How thick mm or Inches are the Radiator support bushings that go between the Radiator support and frame mounted Bracket for a 68 C10 1/2 ton.

ALSO....2 years ago I got in to a wreck....pretty bad...ripped the radiator support out of the 68s right frame bracket and tore the bracket apart. I replaced it with a 70's bracket (its all I could find!!!). it all seemed to line up well aside from the hole being larger..I dont remember.

I am planning on replacing the other side with a 70s bracket as well...if the frame is straight will these brackets line up center and height wise as the 68 brackets? I know the 68 and 70 bushings are way different...was planning on getting or fabbing the simpler 68 bushings. Just seeing if I will run into any serious problems aside from the difference in hole diameter.
