I failed to say it is an 87
Thanks! I actually have that book but was hoping to be able to find one locally. Hate to order one in and it doesnt have the oil cooler lines. The pics dont show the other side of the radiator.Alot of vendors sell this one

I'd call them first to find out. The add says modification of the support is required to install also. 2 core design.

Just bought the cold case radiator, Kirbans was back ordered so I went with Nick at arizonaGN. my car was running hot in traffic, creeping up and over 210. installed the cld case unit and it doesn't go over 170, very nice radiator. One small mod to top rad support and it dropped in perfect. (trimmed the rubber cushions also). perfect oil cooler hook up and , Although I run an external trans cooler, the hook ups for it are there also if I want to double it up.

The Cold Case alum radiator has provision for the 1986-7 GN trans and oil cooler.
Over the years I have sold hundreds of high efficiency 1986-7 turbo radiators which cool much better than stock, and equal to or better than most of the alum rads.
The copper replacement rad that I sell has the proper stock tanks and fittings and a special HE core, but it does cost more than the alum radiators.

The NOS one I bought 15 years ago from GM had different fittings for the trans cooler lines, and it included adapter fittings for the original lines. Then when you installed the radiator, the trans fittings would force the condenser forward because there wasn’t enough room for both.
If you want oem, have your original recored or buy the recored unit from Nick. I’m not a fan of bending parts on the rad support to install a “stock replacement”.

Can you do a Google search for radiator shops in your area and see if they will work on your original one.
Even then, it wouldn't matter. Like said above, the ''replacement'' radiators have the incorrect fittings. When you add the adapter bushings, it spaces the total stack height to the point of contacting the A/C condenser.

If you’re super picky, you might even go as far as removing the end tanks from your original yourself. I took an original to have recored about a month ago after being disgusted with availability of good stock replacements. Radiator shop absolutely mangled my end tanks removing the old core. I just installed it yesterday, and knock on wood, no leaks.
Very frustrating and surprising that nobody has stepped up to make a quality reproduction.

The fancy alum ones are awesome. Had one on my old GN, dropped right in, cooled perfectly with the a/c on in the FL summers. I run a Fbody one in my T, works just as good, with SLIC, no coolers, I run dedicated aux cooler.
Thats probably where I am at now

Everyone has that "line" that they will not cross, me , it is replacing that crappy stereo with a quality sound system just to keep the interior factory looking. But had no problem trimming the rad support to fit a quality aluminium rad in there. Did it and never looked back, car runs between 160 165 all day , air blasting 90deg day. Paint it black if you want it to look factory, but have other parts in there that shine so no problem with that.

No doubt, everybody does their own thing. I’m willing to deviate from stock appearing on my other cars, but my GN is a 62k mile original paint car, so anything other than stock wouldn’t have worked for me.
