1981 KZ440LTD starter button / switch

Hello all, I am in need of a new starter switch assembly. The actual switch inside is damaged, not just the button. Has anyone successfully installed a aftermarket switch of some sort inside the factory housing? Or does anyone have good factory one laying around? All the push button switches I have found so far is either too big, or too small. Thanks for any help.
