what is the part number for the u joint i need to put a 3/4 14 bolt full floater into a 87 chevy 1/2 it needs 3/4 u joints on one part and 1/2 on the other, i think its a 1310 1315 split U joint? i read about it at coloradok5.com but they will not let me post over there.
Does anyone know where to order this, what the part number is or where to buy it at?

If ya have the 3/4 ton driveshaft, the slip yoke might fit on the 1/2 ton driveshaft splines.

When I put the 3/4 ton yoke on my NP205 (I broke the 1/2 ton (1310) one), I just swapped driveshaft ends. Doesn't vibrate, or anything, any worse than before.

If that works, you can just run a 1350 (3/4 ton) U-joint. Stronger, and cheaper. When I was messing with cars, the conversion U-joints were pretty pricey.

Just walk into a napa store and tell them you need an "Un-even cross u-joint" 1330 to 1350 (I think). Take you line in if you can.
