The Imex Romulins that I purchased states that the "adapter requires washer 5/32 hole x 7/8 NOT INCLUDED" underneath the barcode.
I haven't put these on my CEN becuase I decided to use them on my X-Factor instead.
I think that there used to be pics on the old Wildhobbies archived forum but I don't think that is available anymore.
The Schlesser rally body has pretty big wheel wells and might work ok with the T-maxx wheels as well as the Mt2 truck body.
The JT chassis is longer (if that is the chassis that you will be using) and the front of the wheel wells will need trimming, mine did with the stock truck wheels. Wait until you get the correct arms before you decide to start cutting because the trucks are quite a bit wider than the rally's.
