Bowler

Hi all, I'm building a slabby 1100 rear wheel in my 1100ET and I'm trying to use the brake torque arm from a 1990 GSXR. From all the exploded views I've found I can't see how to mount this arm to the frame. Does anyone here have a picture of it? Or could anyone explain how I need to attach it to my frame (e.g. do I need a U-bracket or is a single bolt enough) Thanks in advance Timon
