I painted the coolant tubes and installed them using t-bolt clamps and silicone hoses. I made mock up axles using the outer GM CV joints and inner Audi tripod joints.  Dutchman is going to make a set of chromoly axles from the inner/outer axles that are tack welded together. I installed the replacement fuel rail (mine was bent) and new o-rings on all eight fuel injectors. When I disassemble the rear suspension to remove the axles for Dutchman, I can paint a few areas of the rear chassis and remove several brackets that are no longer required.
