You might try "Bryce" who is in St Marys Washington I think .Used to sell under "cheap Stihl parts " then "cheap chainsaw parts " on flea bay .I've talked to him on the phone and he has a ware house full of stuff .
Of course I've never seen it but "Rotax Robert " has .Now what ever happened to Robert Andrews I have no idea .I used to correspond with him via E-mail but he disappeared a few years ago as have several others .
I think it's Bryce Stodt or something like that .If I can find the phone number I'll send a PM
