W126 Brake Light sw and Hood Pad

[Morocco]

I'm going to replace the hood pad and the brake light switch on my '91 420SEL next week.

Could someone please tell me:

1 How is the hood pad held in place? Is it glued on or screwed on? Anyone done this?

2 Where is the brake light sw located and what is the procedure for getting the job done?

Would appreciate any info and personal experiences.

Thank you!!
