Thank you very much, indeed pampadori and Flat6pac for your invaluable guidance.

In regards to the pin/tappet Part# 915-303-145-00-OEM, the part suitable for the G50 transmission is Part#95030324001 under the name: cam follower.
I've confirmed that from the Porsche PET catalogue Year 1989 (illustration 302-05) part#37
And for the reverse light activator, I found it in the same catalogue number 38, and Part#91461354102 under the name:back-up light switch
