Roof sensor assembly Bolt in place

[MGBoxter]

Boxster 1999 - soft top control - Switch

It appears that pressure on the switch causes one side to come free causing an intermittent contact.

The switch assembly is very lose because of the 2 screws/bolts that hold the assembly in place to the windshield frame go into (2 plastic retainers) which are cracked, so the botlts do NOT tighten and leave the sw assembly lose. When I go over a little bumpp, both windows go down a few inches faking the sensor to think that I want to put the top down.

What I am looking for is the parts # for the 2 white plastic retainers where the screws go inThank you

Are you referring to the nut in the windshield header which has become split like this?

If so, and I hope not, it's only accessible by removing the windshield. However, you can replace it with a better than OEM set-up using nutserts/pemserts. There's a DIY on how to in post #5 of this thread:
