Pinion angle help

[HeavyMetal72]

I am using 6" springs to lift my K5. I know I may need to shim the axle up, but need a crash course in the basic geometry of it. Any help would be appreciated.
Thanks

Rolling the pinion to be 2 degree's lower then the driveline angle is needed - here's a link to my driveline tech section hope that helps-cutting and turning the diff is best- Jess

Ditto what Jess said. You can correct the rear easilily. The front correction requires a good 3-piece shim kit (check DIY4x) but you will quickly loose caster.

Thanks guys, I cut the perches off the 14bff and am ready to weld them back on when I make sure I know where they need to go. I will check out both links.
Thanks again.
