Curious what you guys used to plug the holes in the A/C core that is mounted in the firewall? (the one that is on the pass side that has the 2 aluminum pipes that pass into it)

I don't really want to leave the holes open for condensation, moisture, and rust to accumulate especially if I ever plan to reinstall the A/C on the car. Anyone find some threaded plugs that fit where those fittings are? Remember sizes? Thanks.

 

A small piece of bendable heat shielding (or even aluminum foil) will work in a pinch.

 

Metal dryer duct tape works great

 

I honestly plan on getting a set of aluminum caps with the correct thread and have them anadoized red for my car. Hopefully I can find what I need.
