OK, finally got arround to figuring out how to post pictures (not that it took much effort, but I’d been lazy about it), so here goes. I also considered using channel, and actually have a piece that fits over the maggie mounts perfectly. However, it didn’t leave me enough width to put in the little hole for the spring retension, so I went with the plain angle. The black on the angles is just some electrical tape to prevent rubbing, which seems to be adequate because there is no movement once it’s tightened down. The little tubes are aluminum spacers I found at the hardware store. They fit almost perfectly, although there is a tiny bit of sideways slop in the system along the length of the screw. Length of the tubes are as bought, which is just about right. I also bent out the aluminum angle pieces to better fit the contour of the weld along the maggie bracket, and prevents any rotation of the angle.
