Does anybody have a pic on how the rear speaker/defrost options plate is attached in the trunk of a 70 Challenger? Or any knowledge of how it goes?

Don't know if this is correct?, it's how I installed mine. I was told the hose should be cloth and I have a cloth one, but this plastic hose was in better shape so I used it.

My stock...

THANKS Challenger 1!!!!! I really appreciate it!! I have one question for you- maybe you can help. In your first picture, the mounting tab on the right( it would be the one farthest back toward the rear of the vehicle) what does that mount to? I replaced the panel below the back window on my car- did I miss taking a bracket or something off that that would mount to? seems like mine is just hanging out there like yours is, but i see you have a screw through yours. Cant tell from pic where it goes. Thanks again! P. s.- I like that color of your car!!!

That bracket attaches to the package tray to help support it. Exact details on the fastner? I can't remember without looking.

Thanks again!!!!
