Well, I'm totally bummed out. I thought I was a heartbeat from being out on the trail. Looks like I have a ways to go. As I posted in the other threads called "How big can you go on shims?" and "A whole boatload of doubler question", I found that my front and rear driveline angles are causing me major headaches. My setup is a D60 up front on 6 inch TC springs. Out back is Corp14ff on an ORD shackle reversal, 4 inch TC springs, and an ORD one inch zero rate (9 inches total lift). I have a HAD rear driveline with 1350 CV at the TC and 1410 yoke at the pinion. All of this is on a 76 Blazer. To summarize my solutions, I'm going to have to cut off the rear Corp14 perches and re-weld them back on after rotating the axle to accomodate the 11 degree difference that exists now (Better than too large of shims). Prior to doing that, I need to deal with the fact that the front is also way off. After speaking to Jesse at HAD, I plan on doing a doubler setup. This will move the front TC output about 6-7 inches back. This will help my steep front driveline angle, (which at this point is 28 degrees with the 4 degree up from the TC, and the 24 degrees down on the shaft), and also give me the benefit of having a doubler. It also gives me more clearance since I swapped in a 700r4 and now the 1310 CV is about an inch from the tranny pan. It will move my rear TC output back but I should still be ok. However, looking at my front, in order to get my front pinion in line with my driveshaft, I need to correct a current 19 degree difference. There is no way I'm going to safely accomplish this with shims. According to a few folks I've talked to, the proper way to do it is to remove the inner C's, clock them, and then re-weld them back on. This is because even if I were able to change the perches 19 degrees, the outer kingpin setup would be rotated so far that the geometry would be a major problem and put undue stress on the uppers(?). So, the solution is to rotate the axle, re-weld the C's back on, cut off the driver side perch and clock it, then machine a matching angle onto the passenger side perch. The big question of the day then, where in the SF Bay Area is a shop that can do the cutting and re-welding of the C's and then machine the perch?
