How to find out what gas tank fits my 1969 Honda CB350?

How do I find out what gas tank fits my 1969 Honda CB350?

If you know what variant it is (e.g., a K3), you can see if one of the diagrams here has the part number:

If you don't know the variant, you can use this website to find out according to the VIN:

For example, here is the fuel tank for a CB350 K2:

IIRC, almost any cb350 tank should fit. I believe my frame is a 1969 and have what appear to be 1973 tins on it. May have issues with seat fit though. If I have time tomorrow, I will compare a few (have 3 CL350 and 2 CB350 at out shop right now).
