I've got everything mocked up, with the truck's weight on the springs. Right now I've got 6 deg down on the t-case (fairly stationary)... so I put 6 deg "up" on the axle pinion (not welded yet). That put's my driveshaft at 17 deg down slope. And if I know what I'm doing, that gives an 11 deg operation angle on each of the joints, right? Maybe 12 deg depending on how good my eyes are under a truck on my back. For some reason it looks kind of steep. Should I tack her in place or tilt the pinion up some more. Still running S44 joints (a bastard S44/1350 at the axle). FWIW this is a Short bed K10 with roughly 7" of lift (shackle flip, add-a-leaf, and zero-rate...axle moved back 1.5"). HELP!!!
