1992 Yamaha WR200 compariable too YZ of same year.

I am looking to get a Moose Torque Spacer Kit for my 1992 Yamaha WR200 but they dont have one specifically for that model. They did mention that they thought that one of the YZ models of the same year might have the same engine compenents. Does anybody have an idea if that might me true?

Thanks for your time.
