Need a 350x part

[Kevin in Ohio]

I was out riding today with my '85 350x and was hitting some bigger jumps. Noticed a clancking sound when landing. Stopped and looked the bike over and noticed my tank was loose on the front. Seems the metal sorround that is spot welded to the bottom of the tank and sorrounds the rubber cushion let go.(broke) Naturally, I can't find it anywhere. My original metal tank is fine. Does anyone have a junk piece they'd be willing to part with? Started looking on Ebay but don't really need the whole tank. Any leads appreciated. Kevin
