I apologize, this weekend was busier than I expected. I just got out to the car with the camera again. The passenger side horn is NOT opposite hand of the drivers side horn like I thought. I just glanced at it quickly before, sorry about the incorrect information I gave you before.
Attached are a couple pics. I didn't have my small work camera with me, my camera is larger and its tough to get it up in the tight area to get a good pic.
This is from the front of the car looking toward the back. The bolt to the left of the horn is the mounting bolt.
This is from the ground looking mostly upwards, the mounting bolt is to the left of the horn.
This view is from behind the horn looking forward and slightly to the left (drivers side), that's the mounting bolt above the horn.
Again, good luck with it, sorry it took a little while to get these pics up.
