My burb had dealer installed AC, and it had the exact same holes in the firewall.
They have long since been welded up.

I have little to none experience with AC systems, but from what I have seen and learned from the much more experienced here on this board. Is that the 40 something year old vintage AC stuff is quite expensive to restore, and keeping them cold is a whole other talent in itself.

I am actually contemplating the installation of the new AC systems out there, that are specifically designed for these old trucks and use new parts and coolant.

Check out the prices from the vendors on here, since it seems like they are always selling them on sale. Hence, why I have been thinking about doing it.
