That's good to know, I haven't welded my tubes, was wonding if my lincoln
mig 10 would do it, or should I get someone to do it for me, also does it
have to be drained? I put in the one peice axles, but now that I have a
detroit in there I keep thinking about spinning the tubes on it. And now
with my new engine, (first run today), I have the power to do it, what a
difference, may be able to pass someone on the hyway now.

Hi Greg,
Unless you're one heck of a welder, I take the axle out stand it on
end so I can quickly complete the weld before it begins to pull off
center, we know it's going to shrink, I just want it remain straight.

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!
