4\" lift and driveshaft question I've installed a ORD flip with stock springs and a 1" zero rate on my 82 K5. 4" TC springs and 1" zero rates will go up front. Will I have to drop the t-case for driveline issues? If degree shims are needed, where can I buy some, and how/where do they go installed /forums/images/graemlins/confused.gif This is my first attempt to swap axles and install a lift myself. No previous experience.
