65 A BODY Front Suspension help

That C-body housing is going to be too wide. However, some of the C-body and truck axle shafts can be cut down and replined; your housing can be narrowed as well.

As for the front, you will want 73 and up A-body disk front, to include callipers, rotors, spindles, upper control arms, and proportioning valve. You will also want to upgrade master cylinder as well.
