ok... I may sound stupid, but I think I'm right..?

I have a 2007, Yamaha TT-R125. As some of you may know the rear fender is a stub, I say that a YZ 125 rear fender will fit, the other person thinks that I should use a YZ 80/85 rear fender... Should I use the 125 or the 80/85 rear fender thankssss!!
