Tell him to stop backing up or sitting there with it in reverse idling. There is a bronze lined single clutch that used to be available which lasted much longer than multiple clutchs in that location. Try Coan , they may still have some.

What rpm does it begin to engage low? You can adjust that with jet sizing if it's the TCI valve body, or do your own and use Holley jets. If it's dragging due to a too-low of an rpm it begins to engage then open up the bleed size slightly. Also I like to use the nitrided aka "Kolene" steels in a circle track Glide like this as they take the heat better. Frictions have been a toss up for me as to what seems to last, I used to use the Raybestos Blue Plates exclusively for high gear, but anymore I've used Alto frictions. Also, I run the clearance at .015" per friction for high and a bit more for reverse. I ran out of the bronze stuff a couple years ago myself.
