FYI: I made the decision not to put in A/C but go with the original type fresh air heater alone.
Anyone know where the heater hose comes thru the firewall? There seems to be several holes in the firewall but I'mm not sure which ones are the proper ones. All the "extra" holes are being filled in and welded over. Any pictures of heater hose coming thru the firewall on a 2 ton 1951? Thanks again for all the help.
