I know this is an old post, but… I am looking at a 92 3500 dump truck. It is non-a/c. I already own a 98 suburban that had ice cold air , but blew a head gasket… Anyway, does anyone know if the suburban parts will swap over to the older ‘92 dump truck? I can get the dump cheap, and need it for the farm, but I l8ke my a/c now that I’m older..lol Thanks in advance for any response…
