Don, Thanks for the education. Your hands on explanation sure does make sence to swap the thrust block instead of shortening the axle. I've never taken apart a rear end and this was my first swap out. I only wanted to help Marcus with info that I learned here. I'm going to do this swap again in my other '63, 741 non-SG to 742 SG. I contacted Randy's and was told to remove the "Button" that the axle butts up to and I'll have no problem using my axle's. I have a diagram I'd like to show and ask you a question about. Would you contact me off line. Nick Tiberio FuryUs Don Dulmage wrote: > > > ---- Please address private mail -- mail of interest to only one person -- directly to that person.
