take 1/8 plate stock, cut a hole the size of your tubing, so the tubing will slide through it, and make the tab in kind of a P shape and drill a 3/8 hole on the leg of the P...then you can weld a tab off the frame and use high temp rubber or poly to isolate them from vibrations...and of course you weld the bracket to the tubing...works great. and there is no vertical room taken up.
