i imagine most years interchange but are the actual bump stops sold as a part of the spring guide or something along with the nylon washer? i cant find just the stops in any fische.

im rebuilding my buddies forks and the stops are dry rotted and cracking/broken

The '04 YZ450 used a 48mm open bath fork, which used oil locks for bottoming, and had no soft bumpers at the top of the fork. Do you inner tubes measure 46mm, perhaps?* If so, the bumpers are sold under KYB part number 110130000401. The '04 WR450 used the 46mm fork from the '03 YZ, and had these bumpers in them.

* Another visual clue is that the 46's will have a top cap that has a 19mm hex on a flat surface, while on the 48's the hex sits in a slight recess on the cap.

If Yamaha doesn't sell them, SMART Performance and Suspension Direct will.
