well.. umm if you find proper diameter then maybe.. but im not sure about stanchions lenght and how it ends. for example, i had 03 Axel. its stanchions were quite long, one of them ended with oil seal (right one) and left ended with a.. dont know how should i call it. its hole and plastic stick comes through and connects casting and coil spring. so, id say that its impossible because: 1. you probably wont find proper diameter and lenght, 2. if you do, probably stanchions ends wont fit your Sid. id recomend to buy a new fork, for example '04 Axel Elite or smth cheap like that (if you dont ride alot)
