What most people don't realize is that the u-joint straps are designed to stretch and conform the to the u-joint when tightened. Once they have been stretched once, they should not be re-used. Using old straps can prevent your u-joint from being held in place firmly and securely. If you have a strap and bolt style yoke and are getting a new drive shaft, you should get a fresh set of straps and bolts. Fits Jeep and Ford yokes, does not fit Chevy or GM yokes.
Fits either 1310 or 1330 but only fits 1310 or 1330 series yokes with threaded holes. If your yoke has non-threaded holes, you may need a set of u-bolts instead.
Proper torque on the bolts/screws is 15 foot pounds.
If you need these and it's not part of a larger order and you want to save some time and money on shipping you should be able to find these locally at an auto parts store using Spicer brand part number 2-70-18X.
