I have not gone there with any discussion concerning the '63-'66 C20's and C30's simply because it would not be the easiest task to correctly locate the saddles onto the crossmember. If not done very precisely, there could be alignment and steering issues. Additionally, the saddles would have to be either found on a donor crossmember, or fabricated. IMO it would likely be a tossup between performing that much work and just switching the crossmember.
