Don't do that I did that once It failed
The stock CORRECT straps and bolts are a lot stronger on retaining the U joints cups in the pinion yokes than the after market U bolts kits are
Mopar design the pinion yoke to have the U joint cup inserted more than 50% in the yokes so the straps only hold the cups back into the yoke, they are not adding strength to the U joints
Make sure the straps you have are for your U joint size, don't mix the 7260 straps with a 7290 U joint or visa versa
The way to tell iif you have the correct straps for your U joint is they fit flush, not loose or bound up over the U joint cups
