my front pinion angles toward the ground about 7* or 8*. Where should a stock pinion angle be relative to the ground? Shouldn't it point up a few *s? What angle should my c's be at to maintain correct caster? Thanks!

pinion angle question

Your c's should be at 5-7 degrees, the pinion angle is pretty flat but I've never measured it (it certainly shouldn't be pointing down).

well I've got 15* at the c's so would it be ok to have my zero rates in the front milled to act as a 10* shim? That would give 5* caster and the pinion would be pointing up about 2.5*.
Sounds right. If you're running a D60 you'll need a 10 degree shim to run above the passenger spring (to keep the spring plate flat, for the studs on that side).
And IMO 10 degree shims seem a little sketch. How did you manage to point the pinion down this far? Super long shackles?

Well I have a D44 front and the reason my angle is so bad is becasue I have long shackles, 52s, and I moved my axle forword 1.5" so it sits farther forword on the spring which is at a different angle. Combination of all things I guess. If I have my zero rates milled for my D44 I wouldn't need any shims correct?

sounds right to me
Simply put, if you have a C/V front driveshaft, the pinion should point at the T-case yoke. If you have a standard (single cardan) front driveshaft, the pinion should be parallel to the T-case output. The angle of the pinion relative to the ground is irrelevant.
That being said, the amount of caster can limit how far you can tilt your whole axle. If you simply make up for what your spring swap and shackles have done, it should improve both aspects.

Isn't there supose to be a 2* differance in pinion angle if you are running a single cardan shaft? This is what I thought. If this is the case I should be fine with a pinion angle 2* less at the diff yoke than at the tcase while maintaining 5* of caster. I think I have a CV shaft now but I am having a shaft made and I will go with single cardan for more angle. The reason I referenced the ground is because I think it should be on the same plane as my front output of my t'case. Sound right?
