72 K20 Front Axle U Bolts

[Brian 72 K20]

I just realized the second set I got doesn't fit. The first was from tuff country and said they'd fit-no. The second was from LMC, I assumed they'd fit since all they sell is truck stuff-no such luck. Maybe there's a bunch of different sizes of u bolts on these trucks. The big one measures about 7 1/4 x 3 1/2 and the small ones about 6 3/16 x 2 3/4 (or 13/16). Dorman measures the width inside across and the length to the inside of the bend. I'm looking at Dorman 929-839 and 929-715 which are pretty close and I'm hoping just my measuring error.

Can anyone confirm or know ones that will work?
