Your question appears to be worded a bit strange, or maybe I'm just a bit strange. Just confirming you would like to know which number plates will fit an 07-10 model Gasser?
I put a 2010 crf front guard and number board on my 07 without too much effort. You can pretty much put any number board and front fender combo on because they don't interfere with any of the other plastics, provided you can modify them to fit. Usually it just means drilling some holes to get the fender to fit, and making a bracket for the number board.
