Here's the setup on one of my cars. Obviously, these are hydraulic backplates, but the same setup should work on Austin factory backplates. There are three countersunk 5/16" screws though the backplate, these are locked off with nuts on the outside of the backplate which also act as spacers. The steel tubes are brazed to the steel plate which is secured to the backplate with three more nuts.
