Swapping 85 to six lug

[lowhoe]

Im converting my 85 to 6 lug. I already have the front taken care of. Now for the rear i was told i could swap axle shafts from a square body 4x4 8.5" 10 bolt rear. From info ive found on the web the spline counts are the same and the 4x4 shaft is only 1/16" longer than the 2wd shaft. Anyone have anymore info on this?
