    I'm not taking the front of my shit off so you can say you don't think my condenser looks like an sn-95 condenser. You'll have to take my word for it or move on.

    I'm genuinely curious how a condenser that is 2" taller and 7" wider and drop into the same bracket location.

    Edit:
    Let's be real. You can't.

    Now that I'm home and looking at it, I moved the brackets, but nothing had to be cut. The upper brackets are both moved outward, the lower are down and outward. I didn't say it popped right in like a direct swap, and I didn't say the bracket locations were the same, I said it fits like OE. OE means using my brackets, maintaining position relative to the radiator, and generally riding in the same position as on the donor car. I moved brackets, for which I had to make new holes; nothing more. I don't know why you had to cut and I didn't, I only know that 8 years ago, the last time I touched it, it was a fairly minor mod to move the brackets.

There is a screw down in the connector on the switch to do this with, I like 1/4 turn increments.
    This seems spot on. I have a 88 Cougar 5.0 All stock 88 stuff, new cycling switch and adjusted, Vacuumed down and refilled. Changed nothing else, no leaks, not recharged in 6 years. AC blows very cold and keeps very cool. Mine is a black car in KS summers. If I had to do it again, I would do just what He said above. Fortunately mine worked great stock, just as was.

    Ah, I took fits like OE as fits in the same as OE.

    I had to cut because I used existing holes and made ghetto brackets for it. Drilling new holes to lower the condenser would eliminate cutting the upper radiator support. Two methods to achieve the same end - although I think drilling new holes is the better way to go. At the time, I hadn't found anybody who had done it and the internets yet, so I was on my own for the install - and I don't do well with original thoughts!

    My thought when installing it was that if we assume that the connections are in exactly the same position, but the unit is roughly 7 ish inches wider, the mounts should move out by half that from center. Since the unit is also 2 inches taller (the additional 2 inches is along the bottom relative to the connections), the lower mounts would have to be that measurement lower. 4 3/16 holes and 4 1/4"x 1" lag screws later, we're golden. I moved the radiator away for room to work on the top mounts, then connected the spring locks, and supported the condenser with a stand. It made it pretty simple from there to move it around until the position was right and I made holes with an angle head drill, and ran down lags with an air ratchet.
