Power Brake Booster To Firewall Seal for 1969, 1970, 1971, 1972 and 1973 Mustangs with a Bendix Style Brake Booster.

The brake booster is bolted straight to the firewall so any moisture that gets behind the booster may enter the car. This seals the open space between the brake booster and firewall. Any moisture or liquid running down the firewall will be stopped from entering your Mustang's cabin.

If you notice wetness under the pedals or on the driver's side floor, this seal may need replaced. Seals tend to become brittle after time and should be replaced to ensure a dry interior.

This seal fits Bendix style boosters only. Bendix boosters are constructed with two halves that are crimped together. This seal will NOT fit a Midland booster which has a clamp around the middle.
