This is relevant information to almost all aftermarket MC21 and MC28 chambers. The only ones I seem to recall that fit inside stock bodywork are DogFight and some Ethos systems.

Also the JHA 500V chambers fit in the bodywork of an MC28 with no modifications.
But they were made for use with the racing JHA footpegs.
With the stock footpegs needs two spacers 10mm length behind the right footpeg bracket.
