Yep, That's the problem.. If i purchase a aftermarket switch can i use the metal tab out of it and install it in my original 177 switch?

There were other GM cars that used a vacuum h/l switch. '69 Caprice?

Even a used switch may be ok for parts.

Thanks for all the help guys. I silver soldered a new metal tab. It works great now.
