9 1/4 rear?

I have seen articles where they added 8 3/4 tube ends and resplined stock 8 3/4 axles in the 9 1/4. I am pretty sure Moser did the job. There are several ratios available up to 4.56 and a couple of good differentials for your application . Look in the 4x4 mags for more options . These axles were used with big block trucks with 4 spds. They are plenty strong and not as heavy as a 60!
