Scored a cool dual CHP gunrack

[John10608]

The " cone " or metal box that the actual red light sits in behind ( shield ) had a vacume line sliced and pushed onto the shield as a gasket so to speak for the shield to rest against the windshield. IF that is what you are talking about.
It acted as a vibration - rattle stop and kept the shield in place against the windshield.

So yes, the shield does rest against the windshield. The shield rests over, or slides over and onto the red light and should be attached ( or held in place ) behind the red light with a spring that goes from left to right on the back of the shield.

The shield is just a light blocker, so it directs the red light forward instead of to the sides, up and down when it is on. It has no support function at all.

Was that the original question you were asking me about ?
If you need pictures, pm me your email address. I'll get some close up pics for you.
Hope that helps some ?
