Ok, so here is my situation now. Looks like I'm stuck with cutting my Corp14 perches and welding on new ones to accomodate the major degree changes I need for the pinion. However, my front is also way off. Throw in the fact that I swapped in a 700r4 and my front CV clearance is extremely tight. Jesse at HAD suggests a doubler to move back the front TC output to lengthen the driveshaft, provide more clearance for the CV, and of course to enjoy the benefits of having a doubler. However, after I install the doubler, I'm looking at adding at least 6 inches of length to the TC setup thereby shortening the rear driveshaft. So, here are my questions: 1. Does anybody here have a 700r4/NP203box/NP205 doubler setup now? 2. If I add the doubler, I'm assuming I would have to wait until it is installed to see exactly how many degrees I have to clock the new rear spring perches? 3. Is there an easy way to figure out how many degrees to clock the perches once I get the doubler installed since the current driveshaft will be way too long and impossible to install to measure driveshaft angles? 4. 4x4 Iron has gone out of business. Does anybody else make custom crossmembers? According to the ORD site, I need to fab the front crossmember to provide clearance for the front driveshaft. 5. Who makes front 3 piece D60 shims?
