Did some custom fabrication for the hardline sections of the diff cooling circuit to hold the lines down steady to the IRS subframe, and this way there's no stress on the threaded part where it bulkheads through the upper subframe liquid line and using the quick disconnects for the diff won't stress things out either. The fun part was welding them down to the frame. Luckily I had a pneumatic wire wheel and plenty of acetone and the Argon gas for the welder. Came out beautiful once the slag was ground down and everything re-painted.
The bodies of the quick disconnects just kind of 'snap' right into this body clips that I made. I made quite the usage out of a pneumatic burr bit making those things as well as a rat tail file. Made the clips out of 1/16" steel and hogged out a shit load of material from the center once I precisely cut out the outlines with a cutoff wheel. Used a standard bench vice to close up the tangs so that the QDs are held in real tight, but not tight enough to swivel them out if need be (can't imagine I'll ever have to though, but still nice to have that available).
