65 C20 to C10 changeover

[69SCSS]

Quick question. I have a customer truck that's a 65 C20 that he wants to swap to C10 front suspension and discs. Wanna make sure all I need that is not replaceable wear items are the complete control arms upper and lower, centerlink (which I may be able to use the stock C20 one?) and the spindles. I will replace ball joints, tie rods, discs, calipers, hoses, etc., but just want to make sure. I know it's as easy as getting a whole assembly, but trying to avoid pulling the engine. This is going to be stock height and suspension, he just wants it to be safer and more reliable down the road.

Thanks in advance, I just want to make sure the 63-66 are the same deal as the 67-70 swap.
