disk brake conversion Q's

ALL A-body Lower Control Arms WILL interchange from 63-76. 9" drums use a smaller lower ball joint. 62-72 10" drums and K-H disks use the larger lower ball joint. 73-76 disks use a larger upper ball joint, same as B-cars. To convert to later 73-76 disks you need the associated spindles and UCA's.

To convert a 74 drum car (SBP) to K-H disks, you just need spindles, lower ball joints and brakes. Your control arms will work. To fit an OEM style sway bar to a 73-76 K-member, you will need 73-76 "low" tabbed LCA's or will need to fab and weld on tabs.
