Looking for 1981 J10 Fuel Tank

[kbing]

I have a 1981 J10 Honcho model with a 4.2L engine that needs a fuel tank. I've researched it quite a bit and they aren't making them anymore so my best bet is to get a used one. Does anyone have one they are willing to sell or know of a place that I might find one? I've searched many replacement parts websites so this and looking through salvage yards are my last hopes.
