ok i had an 86 1/2 ton chevy pickup, i put a 3/4 ton 14 bolt semi floater in it and i need a special u joint for it, does anyone know what part number it is for a napa or spicer u joint?

Your prabably looking for a 1310/1350 combo, all they will do is take two caps off a 1350 u-joint and put them on a 1310. No big deal. your better off talking to a driveline shop instead of napa. If you don't know where to find one just contact a local semi truck dealer (Mack,Freightliner,KW,peterbilt) they will give you the name of a driveline shop close to you. It will cost you around $40.00 for the u-joint As far as I know there is no actual "part number" for a combo u-joint. Good luck and I hope this helps. also a driveline shop can weld a new yoke to your shaft which is a much better way to go escpecially if you have a lift. That should cost about $150.00
