Quick question before I start this whole thing. I have a 90 30 spline 10blt, I want to swap out the 6 lug rotors for 8 lugs. I have a 79 10blt with all the goodies. I was going to just through that under my k5 but the U joints are toast and I do not want to change em. I have brand new spicer u's in the 30 spline 10blt. My question is can I swap the backing plate, hubs etc from the 79 28 spline 10blt into the 90 30 spline. Are the outer spindles the same. Thanks
