Hi,
As the title says; what's supposed to be beside the blower and battery? My 924S 1986 has just got 2 studs, and I don't know if there's supposed to be anything on the studs.

The previous owner had 2 relays installed on the studs, but I don't know the function of them..

Hope op get some feedback.

 

Probably one stud to secure the battery and one stud to secure the battery harness.

 

The vacuum reservoir container?

 

On my '84 this is where the vacuum reservoir mounts to the body.
