    Went to a spring shop to get U bolts for the HP 60 and decided to get the ubolts for the flip for my Dana 70. Calipers were not big enough to get a measurement so the shop sent me out with a few U bolts they make. The 3.25" U bolts are too small and the 3.5" are too big. Are they metric sized tubes or what? I also measure the tubes on the HP 60. The tubes were 3.13" and 3.88" around. Shop said the axle tubes are 3.25" and the big end is 4" Test fit them on my 60 on the truck and they were a tight fit, got them home and are way too loose on the HP60. Guess Dodge uses bigger tubes than the Ford 60's :dunno:

    On the 70, you can use 3.5 inch U bolts. That is what I ordered.



    If the caliper isn't big enough, just use a piece of string or something and then you can get the diameter by doing some math. I forget the formula. :dunno:



    But the 3.5 inch U bolts fit mine pretty good.

    :withstupid: There is play when they are just loosely on there but they'll bend around the axle once you put some man power on them.
