I am fixing to do just that myself. I have a local junkyard that has a dana 60 with a 4:10 open gear in it, I can buy compleat for 150.00 My plan is to cut the ends, shorten to A body width, install a spool and a set of 35 spline axles. I will do all the work myself, as I do have a narrowing jig, and should get out for about 600 I think.
