I'm looking to do a drum to disk upgrade on a 70 and found a guy parting out a 77 grand prix. I belive the grand prix is still an A-body but I don't know if the spindles are still applicable that late. Any input on transferring the whole spindle/disk setup?

Thanks!

The 43rd Hollander Interchange says these SPINDLES will fit
Apollo 73 – 74
Buick Special 67 –72
Camaro 67 – 69
Chevelle 67 – 72
Monte Carlo 70 – 72
Nova 68 – 74
Olds F85 67 – 72
Omega 73 – 74
Sprint 71 – 72
Ventura II 71 - 41

the 73-77 A bodies use the "tall spindle" that everyone used to love swapping into older Chevelles, despite the alignment and bumpsteer problems.
so, yes, they can fit with different balljoints and (i think) tie rods, but don't be too shocked when the car darts all over the road every time you hit a bump.
