I got the oil return line bracket painted up with POR-15 silver paint, and drilled and tapped two holes in the rear cradle frame to hold the bracket in place.
I decided to use allen wrench driven bolts to hold the bracket against the frame, and while I was at it I pulled out the two hex head bolts on the other two brackets and replaced them with the same style bolts. These will be a LOT easier to remove if I should need to work on those lines for any reason in the future.
This all should keep any of those connections from moving around from vibration and hopefully keep any future oil leaks from developing.
Might be a while before I can get to the exhaust, however. Banged my elbow against a sharp corner of a desk in my den, and my left arm is smarting pretty good from it. So I can't push or pull with that arm without causing pain. Hopefully it won't take too long before it is feeling better.
