Disk Brake Conversion Advice

With FMJ stuff, you need to get 73-76 A body lower ball joints.

Agreed plus Grade 8, 5/8"-18tpi (fine) 2.5" length bolts and nuts to hold the Abody lower ball joints onto the spindles as the lower ball joint 'arm' on 73-74B, F, J, M and R body's are threaded on unlike the A body arm/ball joint assemblies.
