I'm still working on adding IFS to my 1953 Suburban. I would like to use a narrowed cross member and suspension from a 1972 Chevy 1/2 ton P/U. Are drop spindles with 5 on 4-3/4 bolt pattern available for this? I would like the bolt pattern to match my rearend which is also a 5 on 4-3/4 bolt pattern. Any idea's greatly appreciated.
