    What kind of headers, motor etc. This will make a difference. For instance my AC bolts right up with no interference with the headers. I have hooker comps on a BBC.

    Sounds like you have the wrong headers for your application. On some models there's a special bracket that you have to buy to get the a/c compressor reinstalled. But if there's a header tube physically in the way, then something isn't right. [​IMG]

    I have headers and high rise valve covers.
    I had to get a longer A/C belt to allow the compressor to swing farther to the drivers side in order to clear the valve covers.

    Check and see if a longer A/C belt would help you at all.

    Good luck,

    Thomas.

    You have to buy a special bracket. When I put my headders on the special bracket was on back order (I still haven't got it, I think they cancelled my order because it was on backorder for a month or something). I took off the stock rear bracket (the one that gets replaced by the special one) and used spacers and an original manifold bolt to mount the little triangular front bracket for the a/c and power steering pump. It's been holding for over a month with no problems yet, but I need to reorder the special one because compressor is starting to sag a little.

    I used a plasma cutter to cut out the old bracket on my 86.....

    Let me send you a picture of it. I then used an old bolt to secure it.

    The bolt at the lower right corner of the bracket is an original exhaust manifold bolt. It is secured in the head using the last bolt hole at the far end of the head nearest the AC compressor. It goes through the last hole in the headder. Between the headder and the bracket is a steel bushing so the bracket will not compress inward too far. This setup worked great. Again, let me know if you have questions.

    Jegs sells the special bracket for like $15-$20 depending on brand. UPS actually delivered mine within about 15 minutes of my first post and it looks like it should bolt right in between the headder tubes and the headder bolts where the original one can't fit.
