Dana, i failed to mention in my other post those replacement axles are for the 12 bolt rear only..you have the pre 63 axle with the pinion that unbolts from the front..i don't know if anyone makes 5 lug axles for these.if you really have your heart set on 5 lugs ,you will have to do what i am doing..this weekend matter of fact,putting a 12 bolt rear in.hope that clears up some of the confusion!
