In my 69 1/2 ton I'm trying to install the 327 from a 67 3/4 ton truck.

I am using the mount towers(original to the 67) in the 69.

They bolt right to the frame but the motor will abseloutly not cradle correctly on the mounts to bolt up.
I can get the passenger side bolt lines up but off a hair to where it won't thread,and the driver is against the tower in need of going down 1/2" or little more.I loosened the towers both to seen if it would flex a bit and set in but it won't.

Any idea what's going on? Are the 67 towers wrong for my 69 1/2 ton?
