Tom this is mainly for you since you have both but anyone with good knowledge here please chime in. The '61 Fullsized has a rear sump oil pan and center link next to the crossmember, its 1 year only, just like the body style. However the spindles are the same from '61-'64 Fullsized atleast if not into '65 on the Riv. Would it be possible to swap the entire center link and tie-rod ends onto the '64 Riv or is the steering box in different location? Also has anyone ever heard of someone who can make custom centerlinks? Thanks,
