I just put a 4" Tuff Country all spring lift (no blocks or shackle flip) on as well as swapped in a 14bff + 8 lug front conversion on my K5. My old driveshaft is so worn out not even new u-joints will fix it, so I'm going to run a CV shaft from High Angle. I measured today how much I need to move the rear pinion up to point into the driveline. Using my cheapo harbor freight angle finder, I came out with exactly 90 degrees on the pinion, and 26 degrees on the driveshaft, so that means I would have to move the pinion up around 25 degrees ???? Does this sound right? Seems like an awful lot to me. If that's the case I'll be hacking off the spring perches very soon. Just wondering if I measured wrong or not before I go chopping stuff up with the angle grinder.
