Direct Tank Swap Options for 1981 gs850g

[Guest]

I have searched threads extensively for an answer to this question, but have yet to find a definite list for tanks available to swap directly with mine. My tank has a few issues of pinhole leaks and dents that cause me to want a new tank altogether. So what are my options for tanks that mount and fit just as my current tank? I'm not shy about fabricating something for the rear mount or losing fuel capacity in choosing a smaller tank from a different model, but I just want to know if there is anything can can directly interchange. Gracias.

1980 - 1981 GS850G or GS1000G. The 1979 GS850 tank will bolt to the frame, but not sure about the petcock position. It may hit the carbs.
