There are images of both styles of tanks in the 64 page original thread. West coast model oil tanks are difficult to source. I have one.

It is not a direct bolt on arrangement. There is an "L" bracket that bolts to the tank then to the frame via a rubber grommet and spacer. Not likely you will find a bracket, NOS or used. Will have to make one. The details are showen in the Spares manual (pages 44 & 45) as well as in the 64 page original thread.
