No, there’s a grommet on my 75. That seal is for the earlier cars.
I actually ordered it yesterday because of the description but read some conflicting information after. Hopefully it is the right one, guess I’ll know in a few days. ThanksYou never can be sure about reproduction parts but the DMT description sure sounds correct.
If you read the complete link, it shows that it fits 73-76 A Body with the right part number for the 1975 firewall plate grommet 3748634.
