Quick, yet probably stupid, question about firewall holes...

Does anyone know what these 2 holes are for? (middle left) My best guess was a/c. I've looked in two of my other trucks and they weren't there... Any feedback would be great!

Yeah, it does look like someone had intentions on running the refrigerant lines threw there. I have the similar thing on mine as well just plugged them up with some chrome caps till i get ready for the a/c install.

Thank you, I found a line in the rad. Support that looked like it was for a/c and it looked factory to me. So I'm wondering if someone pulled a/c outta this truck...
