I no longer have this AC unit, so now I have 2 holes I need to fill.
I have no skill at welding nor do I have the gear.
Seems like I should be able to find some kind of rubber plugs.
I think the diameter is like 1.5 - 2 inches.
Any idea what I can use to plug these holes?
I had black duct tape over them but it was really ghetto haha

What I have done is to cut two pieces of metal (one for engine side and one for interior side) slightly larger than existing hole(s). Clamp two pieces together and drill hole for no. 10 bolt about center of existing hole(s) in firewall. Clean with alcohol, apply small bead of rtv and bolt to firewall. No extra holes in firewall, fire proof, weather proof, paintable and semi permanent.
