So if you were to use the '63-'66 C20 LCA's on anything other than a '63-'66 C20 crossmember, the shafts would need to be changed to the '67-'86 C20 style.

So....could I just use my existing C10 crossshafts on the C20 arms ?

Or, does it have to be '67-'86 in order to bolt to my 63' c10 X-Member ?

I think I would prefer to use newer style rubber bushing style arms anyway...keeping it 6-lug
