    Hooking up OBS A/C to LS Style Sanden Compressor

    Now that my eng/trans is installed and running great, im focusing my attention on putting A/C back on my truck. Damn Houston heat is terrible!!!
    All I have left from the OBS A/C is the lines.
    I would need Evap core, Accumulator, Condensor, and I want to use the LS Sanden compressor.
    I know about having to cut the frame for the compressor, my only problem is adapting the old A/C parts to the new compressor.

    Hopefully someone has done this and point me in the right direction.

    Thanks,

    Put the factory compressor back in the truck on the passenger top right using one of the custom brackets. I have the sanden on mine and it keeps freezing up inside the cab and I have no air flow then. When it happens I have to shut off the compressor and leave the fan on high to thaw it out, once it starts blowing warm air I can turn the compressor back on. May be a different issue but it's a PITA. This was on my 93.

    Sounds like it wasnt cycling at all.

    Hmmm....I'll look into using the original comp. where would I find a custom bracket??
    I'll probaly look at doing it both ways and seeing what would be a better route to take. And $$$ is always an issue.

    I remember seeing a post where someone used a older camaro bracket, but Ive searched and searched with no luck

    I guess I suck at doing a search cause I can not find any info.
