The FAM doesn't give dimensions, but it has 1/16" vibration dampeners from LMC. I am assuming they are the correct thickness.
The motor is on the stock birdleg mounts and the driveshaft is the stock length (I measured it when it was out).
My best theories are that the radiator is an 1" off somehow, though that would put a huge gap at the top that I don't see in any pictures of stock vehicles or the 58/59 have a different setup and the 55-59 parts are correct for the earlier ones.
I am leaning toward the latter because I know the hood is shorter and hood latch is off by about an inch of you get the earlier hood latch. I already fought with that.
