Hey guys i picked up a 1970 c10 about a month ago and i had a couple questions about the ac unit thats in it. I havent put a belt on it to see if it works but im guessing it does at the moment. its mounted under the dash more on the passenger side and it has the biggest ac pump ive ever seen lol. I was wondering if these were common and if it had any value to it. Its not for sale and i was just trying to see if i had something that would bump the value of my truck up to justify what i paid for it haha. Id like to know if anybodys had any first hand experience with one of these as well so i know how well it works. I hope the value question is allowed in here without me being a premium member as i am not trying to sell it. Thanks for the help and im going to try my hardest to get some pictures up.
