How many different U-bolt pinion yokes?

I do not know if there is a U bolt available in that size. any parts gurus know? I drilled thru a 7260 rear yoke years ago for the moroso stronger thick aluminum cap with thru bolts and nuts, but they hit the driveshaft when dumping the clutch with slicks. went back to the stock 7260 setup, with everything good and tight, no problems running 11 seconds and street, for 35 years. **** breaks when not tight. I guess your driveshaft is 7260, and you need a new pinion yoke, getting a 7290 yoke and a 7260/7290 u joint is another option
