GM changed the taper on the ball joint stud after 1972. The later spindles will physically bolt up but the tapered ball joints (and tie rod ends) will NOT be supported properly. You would need to change to the later ball joints and tie rod ends. The upper ball joints bolt in, but the lowers require machining to fit in the control arms. The tie rod ends require special sleeves to mate to the existing inners. Finally, the later spindles are taller, which can cause problems with alignment unless you use shorter aftermarket upper arms. By the time you do all of this, you might as well go with the B-body spindles and get 12" disks as well.

On the other hand, Speedway Motors has a factory-style A-body disk brake kit that's probably the least expensive one I've seen.

1964-72 A-body (Cutlass, Chevelle, LeMans, Skylark), 68-74 X-body (Nova and clones) and 67-69 F-body all use the same spindles and disk brakes. The steering arms are different but they bolt on so just use your old ones.

The problem is that restorers have driven up the prices of these disk brake sets. If you find an affordable set, jump on it.

Unfortunately it's the same problem with the ball joint taper and the spindle height differences. The 70-up F-body, 73-up A/G body, 75-up X-body, and 71-up B/C-body all use the same ball joint taper (and often the same ball joints), which is different from that on the earlier cars. The only bolt-in spindles are the ones I listed previously.
