3/4 ton to 1/2 ton??

Sorry but that will not work on a '63-'66 C20. Those do not use a round lower control arm shaft and consequently the crossmember does not have the saddles to accept a C10 round lower control arm shaft. I am not aware of a ball joint that will press into the '63-'6 C20 lower control arm and accept a C10 spindle. What I always suggest to the '63-'66 C20 owners, it to simply change the entire front suspension, crossmember and all. Just as Cooper197 and siggyfreud have done.
