    I was recently given a couple of first gen blazers ('70,'72). The '72 has a clean tub and is a CST model. It is equipped with AC. Since this will be a summer only, top off vehicle with a big block when I am done with it, I don't want to run the AC. Can I take the non/ac heater box off of the '70 and put it onto the '72 firewall? I know the plumbing under the dash is different, I am just wondering if this swap is easy or if it is going to take some fabbing. Any help would be appreciated. Thanks

    Heya,

    I have a 72 truck without a/c and a 72 blazer that had a/c and the boxes look the same where they meet the firewall. I dont see why you couldn't switch them over. If your not going to need your a/c stuff. Compresser, condenser, coil...ect. ect. are you going to sell it? My blazer originally had a/c but all the under hood stuff is gone.

    Thanks,
    David

    It's a direct bolt on AFAIK. I spent a considerable amount of time getting A/C parts for my 72 - now that I toook the top off I dont want it back on. Two of the ducts would be wasted with a roll cage anyway.

    I have a couple of A/C systems and a single wall top if anyone is intersted.

    Thanks for the info. I have at least one complete AC set up that I'd probably part with if someone wanted it bad enough.

    Heya,

    I'm interested in that a/c system, like I said before. It's kinda hot here in south Texas....today it was 100deg. with 95-100% humidity.

    Let me know!

    Later,
    David

    wheelin72,

    I visited California a few summers back. I drove from here in Texas. The desert was a blast to see! It was hot....the bank sign said 120+ in one town. But I'll tell you the heat is not like here....the humidity here makes you sweat buckets! It was hot there in the desert but at least it was a dry heat. No sweating!

    I would like to visit California again...that was a very fun trip!

    Later,
    David

    I would much rather it be 110 here than 85 with humidity.
    Humidity is nasty especially without a/c.
