I don't mean to be arguementative, but the U-bolts aren't what I need.
I need spring perches so I may cut off my old ones from the axle tube
to rotate my rear diff up to point at the new location of my NV4500
output shaft.

The perch is welded to the axle. The perches come in different sizes
for the different diameter axle tubes. They said 2.5" 3" and 3.75"
(IIRC) They are pretty much generic. I had ordered some last year (when
I thought I might have time to actually work on the damn thing), but
what I got were perches for a much bigger diameter tube and they
wouldn't work. I measured my tube this weekend at 2.5" in diameter
(don't I wish!). Thanks for trying!
