1967-68 Mercury cougar insulation mat rubber retainers

I only purchased my product items for my 68 Mercury cougar through West Coast Classic Cougars. You can try buying stuff from others but in the end you’re gonna be disappointed everything that Don Rush and his team sells at West Coast Classic Cougars he writes up descriptions so you know what you’re getting and you know it’ll be a perfect fit when you receive it if it’s good enough for their cars, it’s good enough for mine.!!



Thank you, West Coast Classic Cougars yet again for supplying me with yet another quality product!!

More than just Cougar/Mustangs

I really had to push these through the firewall. They fit really tight but they did match the original ones that broke off at the barbed end. Try some light grease on the barbed end before attempting to install through firewall. Used on 1972 Pinto
