SPOA & RockBox ?'s

[ScottFJ40]

I am having a spring over done on the rear of my cruiser right now. I have it at the shop, and Otter, who is doing my fab work, is doing the spring over on the rear, the 4-link on the front, and the full hydro for me.

When I get it back, I will install the rockbox. My main question is how should he set my pinion angle, without having the rockbox there?

hhhhmm......CV rear shaft or standard?

If standard, then the pinion flange outta be in plane with the rear output, and that's relatively easy.

If CV shaft, it's tougher...gotta estimate the location of where the output will be.

IF it were mine I'd have the fab guy tack the perches on, get it home for the rockbox install, then set my pinion angle once you are sure of everything. If the u-bolts are tight and with the perches tacked, it should handle the gentle on/off trailer driving (or, just use front wheeldrive and no rear shaft and don't sweat that at all)

Your fab guy can final weld the perches in just a few minutes....drop the u-bolts, set angle, weld, reattach u-bolts.

Woody,
that's probably what we will do, just tack the perches on like you said.

Thanks for your input.

Rock box only adds 5 inches to drivetrain length so if you really wanted to you could do a mock up to determine the new output yoke location.
