Finally found the right hose (Napa #7240) to get my upper radiator hose and remote fill finished off.
Then I moved onto getting the rear internal cage tied down to the frame rails. First a plated the frame to spread the loads out.
Then a I made a concave plate to match the wheel well sheetmetal and factory botl hole location. Also its slighly larger than the foot of the OEM rollbar to prevent cracking of the body. Then weld a tube between them.
This gives me a spot to mount the remote reservior. While its not a "pretty" spot for the reservior - it will work just fine!
