I have a ProTect Scotts sub mount for you. $75 shipped. It does not have a top cap. You need to use your stock handle bar caps or something like Bonz mounts which I use. This is for fat bars not 7/8".
I have the top Scotts clamp. It has SCOTTS engraved in the front and the numbers 904034 if this helps. The part came in a trade so no more info, maybe others can help you out. Good luck and get back with me.
