Hi!
If your Dana 60's were made in a couple of styles. I have what is called the semi floating type, the axles bear the weight of the vehicle. It came out of a ford econoline van. If you have this type, one axle tube is longer than the other and can be shortened by three or so inches. Moser will shorten the axles for you, or do the whole job for that matter. There is a lot of associated work that goes along with this. Spring perches need to be moved, shock brackets, and so on. I am in the middle of this swap. To date I have sawn the tube, reworked the tube end, and have had Moser shorten and respline the axle. I have yet to move the brackets and such. It is a lot of work...
