U Bolts from a Dakota rear end working on an 8 3/4. Has anyone used this or heard of this.

Yep, I know all this.
I was pointing out the original OP question regarding the 8.25 vs 8.75.

That’s great, but you can buy “Dakota u-bolts” that won’t fit an 8.25 or an 8 3/4.

It would be nice if someone listed the year range and models of Dakota’s that came with 8.25’s/3” u-bolts, since there are plenty of Dakota’s that came with 2.5” and 3.5” U-bolts too.
