I had a the very bike back in the day yellow 99 f700 head shock was f**ked after a few months ended up getting a set of Manitou answer spyder forks for it (elastomers lol) with reducer cups to fit an ordinary headset if i remember correctly they were cane creek reducers. Always keep an eye on the pannier bolt area of the seat stay wish bone, this is where that particular model tends to crack and fail.
