There is no set angle, and alot of different things affect the pinion angle. If I was you I would do a quick search. I just did mine and it is set at 22 Degrees but I went with SOA, SYE and a CV Shaft.

if you are doing a SOA you should already have a good understanding of how it should be setup and why.

A lot of people seem to like to measure it in line with the transfer case yoke then set it 2 degrees off of that to take into account the twist from the torque on the wheel when u apply power to the drive train. I've just seen that setup to be pretty common. I don't know if its preferred for your setup but it will only work well with an sye installed. Do a little more digging around before you tack anything up but nothing should be different with an 8.8 compared to a different rear end.

This.

There is a lot more to this project than just re-welding the spring perch.

None of us know your plans or skill level but we have seen countless SOA project go horribly wrong for lack of planning.

Where's the whole project at?
