Thought I would share some pictures of what the inside of a kickdown switch looks like.
The switch was stuck and needed cleaning. I also needed to replace the plunger since it appeared mice had chewed it or just pitted badly from use but ended up using Por-15 putty to fill in the pits then sanded it down since I couldn't find a replacement plunger.
The bracket in the pic is for a 2bbl and will be replaced with an aftermarket 4bbl bracket through Ames. They also sell the rubber boot to finish the detail. There are 8 indentations on the metal case that hold the plastic piece in on the back. A small blade screwdriver was used to carefully bend them out in order to remove the plastic piece.

Good Stuff!

I need a new plunger for my unit, I swear that I saw someone selling (retail) but now I can't locate. Seems you tried also with no luck.

Thanks for the pics, I'll be after mine soon using this info.

Regards,

I needed a plunger too, so I just installed a Lokar unit instead.
