Brand New 7290 U-Joint Failure

Problem is 3.23 gears.
3:91s going in next week and a little smaller radial tire. 26" tall instead of 27. The drag radials will be sold. at my age I only street drive. But then again look where it broke. The dumbasses at the drive shaft shop but a combo u joint on a 1330 flange on the new drive shaft. It has a 7290 and a 1330 caps. The 1330 caps are 1/16 smaller then the 7290. What irks me is they didnt call to see if I was Ok with. I would have said get the right part, I dont want any stinkin Cheby parts on my car. Its a long drive over there that I really dont want to make, twice.
Problem is 3.23 gears.

Got the pinion nut off today. raised it up high on the passenger side then pulled the wheel and used my pipe wrench and a long breakkover. Pushed with both feet and it cracked loose. :icon_fU::icon_fU:
