All YZ/YZF '98-'03 will slide directly into your triple clamps, and are fundamentally identical (except for the obvious springs and valving) to yours. '04 YZ/YZF are are a larger, 48mm version of the same fork, but will bolt onto your frame by using the '04 clamps. '05's were the first twin chamber YZ/YZF fork, and can also be used with their matching clamps. '06-'07 (except YZ250F) can be used with their own triple clamps. '08 and later (and '07 YZ250F) can also be used, but you'll have to adapt the brake caliper to the fork or use the complete front brake from that year model.
The front wheel should be usable in any of these with the original spacers. In some later models, you'll need an axle to match the fork because the "fat end" is smaller.
