3" spindle for a 90 subn

[low4life1]

Hey everyone I just picked up a sweet 90 half ton suburban. I think it's the same front suspension ans like an 85 c-10 pickup. I found 2.5" spindles for it from bell tech and chassis tech (yuck) does anyone know if there is a 3" spindle available for this truck or can I switch ball joints from another year to make a different spindle work and get 3"? will the rotors and calipers still fit if this is possible? thanks.
