thanks for the comments.
I thought I read on here one time that there were GAS engine trucks/burban/k5's that had that same type of "indicator" mount in the middle of the dash. I want to say someone said it was Brake and Fasten Belts possibly. Not sure.
edit- found the link for the other post here on this. More pix and description of what other gas engines had the lights.

I guess I could do a search...BUT the mount kit for the 6bt just came from the delivery lady! Thought it would come via the Brown Santa...but USPS chicky works well too!
I started to rip open the box...decided to take a few pix. 1) ripped up box 2) goodies! Now...to hide this stuff from the wife!
