Dozer, If you read the links I posted earlier you'll find that there are two A body UCAs. One has a LBJ one has a SBJ. You can put disc brakes on a SBJ upper control arm but then you have to get other parts to get them to work. Plus the large ball joint UCAs give you larger brake rotor options anyway so it makes no sense to go with the SBJ UCAs..at least it didn't make sense to me. Either way I sold my SBJ UCAs in about 3 seconds here on FABO so it's worth it. You can also sell your whole drum front brake system when you're done getting some of your money back.
