74 gas tank cap - other options?

[TAlber8]

will any other years gas tank caps fit a 74 TX650A ? Mine was badly rusted. Tried to powdercoat but was too pitted.

73-75 are the same also TX750 73-74 and TX500 XS500 not sure which years but prolly also 73-75ish about any Yamaha with that rear key cap should work.
