We ARE the manufacturer......... Detroit Muscle Technologies 
 
Description/contents:
This is our NEW, BLACK NON A/C firewall insulation / sound deadener and kickpanel insulation for 66-70 B bodies; Belvedere, Charger, Coronet, GTX, Roadrunner, Satellite. 

The factory fiberglass insulation was yellow. This is a modern looking black fiberglass insulation for a more contemporary look on a resto mod but the exact same size and shape as the factory pieces.

We improved the correctness by adding the small piece of firm black rubber stapled to the lower edge of the large cardboard piece near the accelerator pedal area just like the factory part. It's attached with factory looking, stainless steel staples. After much investigation it appears this rubber flap had no real function. It appears it was just to cover an area of the firewall not covered by the cardboard insulation piece or the carpet. Almost like it was a fix that should have been accounted for in the larger cardboard piece. If someone knows different I would be interested in any information.
