help with suspension kit

The only "rubber bits" in the suspension of an A-Body are 4 Upper Control Arm (UCA) bushings, 2 Lower Control Arm (LCA) bushings, 2 strut rod bushings, 2 LCA bump stops and 2 UCA bump stops. These parts are the same for all years. Sway bar equipped cars will have 2 bar and 4 end link bushings.

Typically the upper and lower ball joints are replaced when rebuilding a front suspension (73-76 disk cars had larger upper ball joints, 9" drum cars had their own small lower ball joints). Steering linkage parts that are typically replaced include 2 inner and 2 outer tie rod ends, Pittman arm and idler arm (steering arms have 4 basic year groups 63-66, 67, 68-72, 73-76).

A complete front end kit will contain all of the above mentioned parts. I'm not familiar with the company you ordered from, so I can't speak to what they offer. I have first hand experience with PST (a FABO vendor) and Espo Springs 'n Things, and would recommend them.

Torsion bar boots, brake hoses and wheel bearing seals should be on your list as well.
