I have a 53' 1/2ton 5 Window Chevy P/U that I am installing a 73'12 Bolt rear axle and a Muncie sm465 4speed tranny in out of a 73' donner. I bought a angle finder and measured my rear end pinion andgle at 11 Deg. up angle with the stock perches. Since the 53 needs perches on bottom I welded new perches on the bottom of the axle at the same 11 Deg. Up angle. It fits great in the 53' But now my question is what angle do I wnat the tranny to have? My guess would be 11 Deg down angle so the tranny and rear end are on the same plane. Is this correct for longest U-joint life? Should I shim the spring perches on the rear axle or shim the tranny crossmemeber to got them in Phase? Thanks for any advice this is my first custom install of this kind.

You always start with the engine/trans installation. You level the carb pad on the intake manifold (if carbureted) for optimum float level/bowl fill.

You then shim the rear to match the engine/trans angle.

Thanks both of you, this helps tremendously. I could NEVER do stuff like this without this website.
Merry Christmas to all and to all a good night!
