9" rear in a jailbar truck

Maybe this description is a 'strap', but on my '92 F350 flatbed the u-joint is secured by an actual strap like small bar stock with a hole at each end and a hump in it. Then allen head cap screws threaded into its yoke. No wonder that old Chinese guy said a picture is worth a thousand words.

There's at least 3 different pinion yokes (that I'm aware of - maybe more) for 9" differentials. Only skimmed thru this video but it looked like it would help you figure out what you're dealing with in that regard.

This seems like the style of u-bolts you're describing - again some differences in the sizes:
