Ironically, I had a 2000 Hardrock Sport which I converted from threaded to threadless for the sake of installing a rigid fork. Here is my thread:
fork replacement, need help 
I am also assuming it’s a 1 1/8 inch as that is what dabac quoted me. As I stated earlier, I don’t really care about the travel that much. I will be riding off-road so I do want some shock absorption but I’m not going to be pushing this thing hard down some technical down hills. So travel just isn’t that critical.
