archive says its 1.120" shorter (axle CL to pinion flange) but that (in effect) is a nominal spec since driveline tolerances vary greatly (that dimention should be OK but everything else will skew it). Planning is VG but on this deal when the times comes I would swap in the dana first then mockup & get a C to C dimention that you need & then find one that is with in range (gives correct end play) or have yours cut down and balanced. EDIT No zerk (solid/no grease passage) ujoints are the strongest & may or may not be needed for your app. Spicer is a good brand & a few others. confirm that the ujoints move freely thru their travel when you get the shaft back or if you install em and you want the zerk to be in compression
