Yes I live in Newport PA. Narrowed the cross member
I have both types. I had this one powder coated. Once I put the box in place and put this support into place I don't think the radiator will bolt in. I chose to narrow the cross member rather than a notch out. I ask because I thought I read some where that the angle of the radiator to engine fan is changed by the support. Some thing about the way the engine tilts in the 4x4 so the radiator must tilt to properly align the fan blades distance top to bottom of the fan ?
There are only two radiator supports for the '75. Actually same applies to all 73-77 F100-350's. The one for the standard cooling and the other for the rest.
The narrow radiator opening is P/N D3TZ-16138-D. The one for the wide radiators is D3TZ-16138-B.
I see the two different openings, have two different part numbers. Then what is the one I have pictured ? Google the numbers you provide and they are NOT what I have. Old thread in this forum " super cooling" has a Ford part listing displayed. It does not show the different applications for the support I have.
What radiator support is used in a 75 highboy with a 360 ? Measure the radiator.
1973/78 F100/350 with round headlamps: TWO different radiator supports, TWO different FE fan shrouds, several different radiators.
The Super Cooling radiator uses a different support and FE fan shroud, because both have a larger opening radius than the standard, xtra cooling and A/C radiators and their support..
Super Cooling radiator has a HUGE top tank, it's wider and deeper than the other radiators.
Super Cooling radiator is approx 26 1/4" wide by 24 11/16" high. The other radiators are also 26 1/4" wide, but their height varies from 18" to 19 3/4."
btw: There are no part numbers marked on parts after 1956, just casting and ID numbers when applicable.
There are no part numbers on radiator supports unless it was replaced, then the part number may be printed on a label that is glued on, or the part number may be stenciled on.
mikeo0o0o0 gave you the ONLY two 1973/78 radiator support part numbers that were used with round headlamps, there's nothing else.
1978/79's with rectangular headlamps use a different radiator support and there's only one: D8TZ-16138-A
So, all tall side flanges are super cooling and all small flanges are normal cooling ? Does a 4x4 require a 4x4 radiator ? I have a 77 camper special 2wd super cooling radiator. I read some where about the angle of the radiator to the engine. Anyone familiar with this ?
If there are only 2 core supports that pretty much rules out any angle differences. I don't see why there would be a difference in angles anyway, and if there was it would be very minimal.
My high boy is the tall flange style, but it has factory air so it would have the heavy cooling. I assume without factory air it would be standard cooling. so you should be able to use whichever core support fits your radiator.
I don't see any reason a 4x4 radiator would be any different since there are no differences on where the hoses enter and exit.
Ok. Very good. It has to right the first time. I am sending this radiator ( super cooling 26x24 ) to be rebuilt. 900.00. I want the original radiator look. I didn't have a complete highboy to start off for comparison. When doing searches online you get many opinions. At Carlisle Truck Nationals a fella had cut His frame, so I copied it. Just looks cleaner than a notch. Here is what was said, 2WD F250 engine sits level in chassis. 4x4 engine is slightly tilted ,the fan is an upward angle. So for the fan to be spaced 2" and flush with the radiator the radiator must tilt ( top toward fire wall ). So I don't know how the tilt was achieved radiator brackets or the radiator support itself. But anyway I'm soon to find out if that was just a lot of over thought I found on the web searches.
I'm with you on the original look, but can't you buy a new copper radiator a lot cheaper ? nothing says screwed up mess like a Ronco aluminum radiator when you pop the hood.
The radiator does tilt at the top towards the firewall for sure. but so does a 2wd the engine sits at a definite angle . I looked at my 2wd parts rig with super cooling and the core support radiator flanges are about 1' wider at the top than at the bottom which gives you tilt . the radiator is gone so I can't say on that .
I think you got all of your important answers, but thought I'd add some details.

No. At least not for some years. My '79 has the core support with the small flanges and the radiator with the mounting brackets. It's a Camper Special and had the big radiator from the beginning.
When I bought it however it had a small radiator because the owner could not find one locally when it sprung a leak on a trip he was on. Later I replaced it again with the big radiator that it has today.
Both were the correct mounting scenario, but when ordering the big radiator I kept getting the type that mounted to the long flanges like in your first image with the new (or just painted?) core support. They finally got me a new one with the correct mounting flanges.

Never heard of any difference, but never looked at the small details either. Any time I'm under the hood of one of these trucks I always look at the radiator first to see if it's got the big tank or small. But never looked for any other differences, such as transmission cooler lines or anything like that.
Never saw any differences between a 2wd and a 4wd that were visible though.

Super cooling radiator: 26 1/4" x 24 11/16." // Other radiators: 26 1/4" and between 18 - 19 1/4."
Thanx You guy's. All this talk of tilt may have been for the square head light 78-79. Basing that on what Paul added. and Number Dummy said the 78-79 supports are different that 73-77. As for the new copper radiator,I didn't look into one. When I called the radiator shop about a rebuild they didn't mention selling a new one, other than aluminum. I will check on a new copper one Monday.
