Good morning Fifi, and a warm welcome to the forum. Its always nice to welcome another Scott Bonnar owner to the forum. grin
I hate to be the bearer of bad tidings but to my knowledge the replacement metal (after-market) gear is no longer available as the firm who made them has closed down.... cry

Maybe someone in the future will tool up and re-manufacture... Only time will tell...
Once again Fifi, :welcome: to Outdoorking!
cheers
