I have to say that the A/C system in Black Jack reminded me of just how well Ford designed these A/C systems. That thing and the one in my F250 are in another league compared to the BMW or my Saturn. So, I recommend use the stocker and don't fix what ain't broke.

That's easy to say for a stock 5.0 for which Ford designed the cooling system. Also; in '96; the Mustang was issued a tsb for overheating. The major part of the fix was switching from the fin dense '96 condenser and going to the '97 unit.
I'm speaking from experience as I live in Phoenix. If you are seeing ambient temps much less than 118°; you can possibly get away with the stock cooling system. I was seeing coolant temps of 235° within 2 miles of driving with the ac on. I was able to drop that temp 20° with the changes I made.

Apparently my ex-husband made that mistake.

I don't have a year range but be forewarned; many of the advertised units are not the correct one. There's a seller on Ebay that sells NOS '97 condensers. I just learned today that the LMR unit is supposedly the correct one. There's two versions...a piccolo style with dense fin count and the modern design with 16 fins per inch. If you Google '97 A/C condenser; you may find the NOS units on Amazon and Ebay. They are pricey though.

Great Info! This insight was extremely helpful. I was hoping to get away with a Murray from O'Reilly's or something. I have recorded the numbers in my notes for later though. Parts store A/C stuff used to be a disaster 20 years ago, but it has gotten way better.

Well, if it doesn't fit, you send it back and tell them to keep trying
97 GT is no unicorn? Or is it?.
I've been down that road and that's how I know the info posted above. The true '97 GT condenser is difficult to find. The aftermarket sells units that are completely different than the originals. For instance; they have no holes in the ends to attach the rubber seals that go between the condenser and radiator. Those seals are very important.

I think they're a little easier to get off

The only change you made was the condenser?

I know. I mean, I don't have aclue about SN95s, but I'm having a hard time accepting their a/c and cooling systems were so bad. Is this real, guys? Not sure I've ever heard that about SN95s before.

He listed a couple of mods that helped in an earlier post. I have all those mods except the condenser. The biggest help I ever got was swapping to a high flow thermostat for $10. My car is a serial high temp car. Can't speak for all SNs.

Gotcha. My sn95 dropped in temp a good bit going to an aftermarket radiator and high flow thermostat.

So if you go to lmr and order a condenser for a 94/95 mustang it’s the denser core, and not the updated one per the tsb? Same goes for a 96-98?

Matter of fin density and overheating?
Hell, they (jmac) or (1-800-Radiator) would be out of business in 5 minutes if they made parts that did not hack the mission
How many so called wrong? ones have you installed, and had trouble with?
You can't just sit back and say it will not work
You'll never get anywhere
And be hot with no A/C in the process

Keep in mind that the cooling systems in these cars were designed for their less than stellar HP. In stock form; the 94-95 models cooled just fine. I bought my car in bone stock form and drove it around in the Phx heat before tearing the engine down. These cars are no different than Fox Body cars when it comes to trying to keep them cool after engine mods. More HP = more heat that the cooling system needs to shed.
The A/C systems are fine. Nobody claimed they aren't. What I've been saying is the newer condenser design is less fin dense and allows more airflow through the condenser and radiator. It's that simple. If you look at the condensers in modern vehicles; they are designed like the '97 and newer GT's. Ford dropped the fin dense design in '97 for good reason.
Have you Googled the '96 GT cooling system TSB straight from Ford?

Dwain on the Corral just ordered a '97 condenser from LMR. They provided pics that look like the real deal. We'll know if it's the correct one when he receives it. Here's a '94-'95 A/C condenser. It's fin dense like the OEM one:
