Firewall plugs for 1974 Plymouth Duster

[Zachary Hall]

What plug can I get to cover this opening in the firewall next to the windshield wiper motor? When driving I get some airflow into the cabin. Is there a rubber plug you can get?

Thanks

The opening that is next to the wiper motor is for the heater core tubes. Don't know if Chrysler made heater delete plug in 1974.

You're probably going to have to make something to cover those holes. Apparently, there's no heater box in the car and that's what left those holes.

Thanks for the information everyone. Ah that makes sense JDMopar. Currently the car doesn't have any heat or A/C. The car was gutted of all that before I bought it. I do want to add a new heat and a/c system in the future.
