It's not that easy on the '63-'66 C20/30's. The '63-'66's use a flat LCA shaft, so there is no saddle to locate a later model LCA shaft. I have not had the time to verify whether or not a disc brake lower ball joint will press into a '63-'66 LCA. If they will, that definitely would simplify the conversion.

one thing I see a lot of with guys switching the entire crossmember out is that they seldom rebuild the "donor" so just changing out worn parts for more worn parts.
If you're going to tear it down and install new ball joints, etc, no need for the extra work of switching the X member.
Just my two cents worth.
Too bad no one close needs a completely NEW disc brake C-30 FE My truck got totaled about 500 miles after rebuild. Everything including the control arms are brand new.
