Picked up some strange solid 7260 u joints to replace the hollow ones I have,good idea. I picked up a u bolt kit to replace the straps but not sure if there is enough meat on the yoke. Is this a worthy adventure and anybody do it? seems like a popular mod with the jeep crowd Steve

I would not. If you really want U bolts, get the appropriate yoke. Having said that, if you're still using 7260 U joints, you probably don't need to change anything. I ran in the low 11s and high 10s at 3700 lbs w/ the stock style straps and never had an issue, but that was w/ 7290 U joints.
I'm not sure how fast your car is or what combination you're running though.

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

Thanks Guy"s I passed on that mod, didn't look like a smart idea to me. Good t know the straps are a strong design but probably going to upgrade to 1350 driveshaft abd yoke over the winter

That is the correct way to do driveline upgrades with matching parts

I know I,perials used the U bolts on the ones I had.I saved at least one to change the strap one on y 65.Cant remember what rear they used IIRC mine were 489s

Yes! Imperials use U-bolts. I have a -742 house from a -67 Imperial.

As I recall those Imperials one's aren't 7260 or 7290 though I want to say Spicer 1330.

, I think that is the correct I.D.
Some of the street hemi 4 speed cars with Dana 60 had that yoke also
