Thanks for the reply 3B the 56 axle is from a 3/4 ton which I think is the same as the 1 ton. Re-drilling backing plates and making spacers is no problem as long as the hubs will interchange. I think I'll get the tape out and do some keen measuring and see what happens. If none of the parts swap out I may cut the 56 axle down to fit and stir up all the you can't do that people.
