I don't have pics yet but I used steel bar & made a vee with bottom running parallel to muffler & top at angle same as rear shock. Overlapped them Welded onto each other from behind to keep neat.
Holes at one end of each bar to match frame lugs & one at over lap for pegs. Rounded ends with grinder & file & painted satin black & had a chrome boot guard that I fitted over top. Had to buy longer bolts & put a spacer on top of bracket top make plate level . Bottom bar 18cm long, top 20cm. Drilled holes in plates first & screwed on lugs then overlapped the joining(Peg) end & clamped with vice grips & marked with pencil to get angles. Hope this helps, will take a couple of pics & see if I can attach to a later message . Lozz
