C20 Spindle Swap - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Sixxer · 08-01-2010, 07:28 PM

I searched around but couldn't get a definite answer. I have a 1964 Chevy C20 and I have a complete 5 lug disk swap from a 1972 Chevy. The issue is should I be installing 1972 1/2 ton ball joints and tie rods or 1964 1/2 ton ball joints. I know most people recommendation is to swap all the control arms but I have buckets for bags welded into these arms and don't want to loose that, so much time and money down the drain if I was to swap them out. Anybody have any ideas here?

Your balljoints should match your spindles, IIRC. I dont know if the b/j will work in the 3/4 ton arm, however. I seem to remember reading that the a-arms have different size for C10 versus C20.

There are a few on here that know for sure. Cap't Fab will probably chime in at some point.

Ok thats what I was thinking but the A-arm throws that off. I was looking for a direct answer and I only found 1 post about it and they were questioning it, not answering. Thanks for your help sir!

There was a disc brake reference thread that had a ton of info about suspension stuff. Maybe someone can pull it up...I dont keep threads.

The balljoint holes in the C20 arms are larger than the C10 balljoints. I believe you could do this conversion using the spindles, rotors, calipers, balljoints, etc from a '88-'98 1500 series truck. The one drawback there is you will have metric wheel studs on the front. Otherwise you will have to change the lower control arms.

Well that's just not going to work. I've researched all over and it looks like several people in 67-72 gen have reamed out the opening on the spindle. Is 1.5" per foot the right reamer?
