12\" lift caster fix i put the superlift 12" lift in my 79 blazer and i'm going to swap the 10 bolt for a dana 60. i have a turbo 350 w/ a np 203. i have six degree shims and need to angle the axle more so that the driveshaft will fit. can i get bigger shims or stack them and also how much will i have to get the knucles turned? should it be the same amount as the shims or should it be a little more positive? i'm going to run 44" boggers if that helps. i know that i'm going to need a custom shaft. i don't want to put the 60 in first, then have to take it back out to get turned.
