Brake Switch Trouble after WJ Booster Install

[howeitsdone]

My brake light switch is not triggering the lights after the swap. I can push it up or down and they come on, but nothing is causing the switch to do that on its own when the pedal is pressed.

 

The flat spot depth is exact to the original. I've tried all 4 combos of rotations between the booster and switch as well. Not sure what to try next short of having to swap the pedal and switch out for a later style.

Put in the GM/Caddy style switch instead. Reference here:

Thanks for this. I figured I'd have to mod something else.

 

Unfortunately manual transmissions don't have that bracket. Has anyone else rigged in an alternate brake light switch? Where did you mount it?

I used a cruise control switch bracket back when I did my 90 and a brake switch from a grand waggy to trigger it.  that was over a decade ago though, so I'm not sure if I have pics.  I'll hunt around.

Update:

 

Removed the main plastic bushing and works now. After a lot of reading online, the brake switch needs to be able to wiggle a little bit. Technically, the 5/8" hole that you drill should actually be slightly larger. Guessing Metric vs SAE here and should be 16mm.
