I pulled the cover off of the switch and noticed that the housing to the tumbler was broken and hose clamped together.I took the clamp off and the top half of the housing and the tumbler came out along with aplastic part with worn looking contacts that must have been mounted in there but I cant tell how. I have a donor car how do you remove the switch? I'm going to need the housing and all since this one is broken in two.
Does that plastic part that you mentioned, look something like this?
