I'm a new member and this post is a little late on G15 frames but outside of the head stock bearing area a little taller and the angular lug for the steering lock, the upper front mounting lugs on the down tubes are moved up about 1/2 inch and the right one is flipped 180 so it is offset to the outside instead of to the inside for the Norton engine.  The mounting points for the Matchless singles and twins are the same.  Any Matchless swing arm will pin onto the frame early late or Norton style.
