Hi Saskatchewanian
Sorry for not replying to your Q’s.
Yes the KH top plate fits to a Thompson very well, you just have to angle the holes in and file the bottom a little so the bolts will angle in to the kh plate. I also make up some new tube nuts from 10mm SS rod, and drill and tap with M5x0.8 to fit the Thompson M5 bolts.
As for the brake brackethttp://http://www.unicyclist.com/forums/showthread.php?t=46326&page=6 I hope this help’s with set up?
I have damaged the cross over hose and have had a number of UPD with a stone/rock sticking in the tyre Its stopped at last until I find a BIG stick? Yes it fit’s into the bleed hole at the lever and You just have to get a second bleed bolt fit the brake cylinder.
Removing the seat? why?
