1967 gas tank filler cap and rubber insert

I'm looking for a plastic gas tank filler cap and the rubber insert for the filler neck on my '66 250..I'm expecting that they may only be available , if at all, in Sweden..?

If your tank is plastic then its not stock. The gas cap on a stock metal 67 tank was a Cawi gas cap. Same cap that was used for the next 20+ years. Available on Ebay, Vintage Husky, Husqvarna Vintage, and a whole bunch of other places.

Sorry Crash.. misleading heading..it is actually for a 66.. and it is not the tank that is plastic, it is the cap..and it just pushes in ..not the automotive twist and push type..

I would try contacting John at Vintage Husky http://www.vintagehusky.com/
