Radiator - Why in the world???

I'm looking for a radiator for the 1972 F250 2WD 390 and I see Cold Case radiators mentioned. I haven't checked them yet, I find one; the overall Core and Radiator dimensions that look good!
For the existing radiator (as close as I could reasonably measure)
Core Width 26 1/4 (Cold Frame really really close, could be my measurement is a little off)
Core Height 19 1/2 (Cold Frame, Spot on)
Overall Height 26 1/2 with cap (Cold Frame spot on)
Overall Width 29 1/2 (Cold Frame spot on)
Thickness about 3 1/2 to to 3 3/4 (Close Frame 3" - no worries)
All should be good but to since up I need the mounting bolt locations.

Do you think I could get any relevant information from them for what follows.
On the existing radiator the mounting flange is about 1 1/2" (grill side)
The flange engine side for the shroud is about 3/4"
The distance between the radiator mounting bolt width is 28 1/2"
The Height between the radiator mounting bolts is 11 inches
The distance between the shroud bolt width is 27 1/2"
The Height between the shroud bolts is 15 inches

Nope, they don't have a dimensional with that information and the fellow on the chat line couldn't answer the questions, in fact it was about the same as dealing with an overseas support line, except it wasn't overseas.

Summit Racing doesn't have a dimensional drawing for their radiators posted.

Why in the world would you not do that, You pay to have them manufactured, to make them that information is required!

I'm using one in my coyote swap. The mounting flanges align up perfectly with the radiator support. So it should not be a problem if it's listed to fit your truck. Mine being a engine swap, has a 1 1/2" flanges to match the ports on the coyote engine. Also these are rated for 700 hp so plenty of cooling capacity. Mine does not have the transmission cooling lines, have to use a external cooler if auto trans.

I emailed Cold Case and got a better result, while I didn't get the shroud bolt height, since only one measurement was given, all 3 of the other measurements, radiator bolt width and height and the shroud bolt width were all within 4mm of mine, well with in the error limits of my measurements.
Here's what was given to me.

"The shroud holes are 703 mm . The mounting holes are 727mm and 279mm apart."

That makes it worth taking the chance on. The thickness of the radiator is listed at 3" mine is somewhere between 3 1/2 to 3 3/4, nothing that I see that will create a problem, the worst case might be some new hoses which would not be a bad idea anyway.

This is the link to the radiator and it's still a mystery why by default the mounting bolt dimensions aren't listed.

@blue68f100 thanks for letting me know about yours!

You can't tell in the pictures but the mounting holes are slotted vertically. Gives you about 1/2" of vertical adjustment.

Angry Cold case radiator

Be thankful that they do not have an internal transmission cooler. They are doing a favor .After all the problems that mine caused I will never use a radiator’s transmission cooler.
My radiator was brand new when I installed the Coyote and it only had less than 10k miles on it.
It did a nice job of barfing up the water mixed fluid in the driveway. It must have been leaking for some time before it really let go and finally overfilled the transmission. The transmission guy showed me the rusted valve body plate which caused the valve body to start sticking.

That's an interesting story, I should recheck my transmission fluid level and color. I dropped the pan about 3 times a couple years back to flush the system and the truck gets so little use it should be in good shape. There is some seepage at the tail shaft.
Mine does have the radiator built in transmission cooler but the previous owner added a 2nd transmission cooler in series..
