Has anybody installed an 8" lift on their 4X4s? If so, any idea what degree shims I need to purchase?

The last owner never hooked up the front drive shaft since, according to him, it has way too much pinion angle as the axle was never properly shimmed. I want to get this thing set up now before winter gets here and I'm found unprepared.

I know how to measure for pinion angle, as I have done it on a couple cars I've built, but I have no idea what the angle should even be for a 4X4.

Any advice would be appreciated, even if it's to dump the shim idea as it will seriously effect the front alignment and steering. Maybe I need to just spend the money for a double cardan shaft. I should probably look at the shaft I already have tomorrow as I may get lucky and it's already a double cardan.
