My bike is an 81 and the new tank is, from what me and the salvage guy concluded, a 79-80 model tank. He said that the tanks are indeed identical except for the threaded bung for the petcock. My petcock nut I.D measures out on the caliper at .670" (~17mm) and the bungs threads O.D measures .615" (~15.62mm) and I.D of the threads measures at .570" (~14.48mm). Dime city sells a OEM replacement petcock for 16mm bungs, but Im not 100% that mine is 16mm. The measurements are pretty close, but I dont want to spend $60 unless I know for sure. Thats why I was kinda hoping somebody had one lying around?
Heres my original petcock, the one I need will look just like this but the threads on the nut will be a smaller diameter
