hi blueangel, i'll have to take some pic's when i get a chance, but basically the top mount is stainless flat bar welded to the tube and fitted behind the top shock bolt. the bottom of the bars are bolted to the rear footpeg brackets with smaller bent flat bar. sounds a bit crude but doesn't look as bad as it sounds. the tube is 3mm thick and when fitted to the bike they are rock solid. very pleased with them
