Thanks, John.
It does look like the stamped housing has heavy tabs on the side opposite the leads connection points. They look pretty heavy and it would take some care to pry them 90 degrees vertical to allow the plastic body to lift out,,the lever on the back side most likely drives a wiper contact with raised nubs that could be polished (Burnished) with a rubberized abrasive like Craytex. the stationary's are probably riveted to the switch leads. A little lithium lube and re-crimp and good to go. I am not a 4sp guy, do the vendors repop this thing, as that might make it not worth the effort, unless it looks like a submarine hatch switch in comparison ha ha ha
