The stock shaft is a hair to long. It will work but if the chassis flexes a little(and it will) it will bind up a little.Either grind a little off of the end or get the correct shaft. Tower doesn't carry it you have to get it from www.nitrohouse.com look under the MBX pro parts list. The part number I think is 36100 but not for sure. The stock brace will work, it should have 2 sets of holes in it, you just use the other 2 holes..It is pretty straight forward.
