I seen Blackwidowmotorsports sells new front fork inserts for $32.00 a piece. Both the brake side and the non brake side. When I was disassembling my bike there was quite a bit of rust and some pitting of the chrome fork inserts especially under the area where it goes into the fork. I cleaned it up and sanded it with 400 grit then up to 1000 grit and while it was better it still forming a coating of rust out in the garage which is out of the elements. After 48 years of who knows what kind of storage the original fork inserts while still structurally sound are pretty pitted up and rusty. I could replace them with brand new clean never rusted ones whith a coating of wax will slide up and down way better. Total cost $64.00 plus two new spring retaining pins at $2.50 a piece. A rusty one on ebay woul probably cost as much if not more. It would look like brand new too and be smooth with no rust shiny chrome and with a coating of fresh wax before assembling would work much better and not rust for years especially if taken good care of with excellent storage and some maintenance.
