I'm new to the forum and hear you also discuss F-100s. I have a '73 Ranger XLT with a 360 engine. The radiator needs to be replaced and I can't find the right size replacement that fits the core support. I hear they used 2 core supports in that year. The tank is 24" X 24" X 1 7/8". The distance (side-to-side) between the mounting bracket holes is 25 3/4", and they are 11" apart, top to bottom. The shroud I have fits this radiator. Is there a source for this size radiator? LMC, NPD, Mac's, etc. doesn't show a radiator this size. I called Champion - they don't have one this size. The one they show that is right is 27 3/8 wide. My opening in the core support isn't that wide. I'm trying to avoid altering the core support and buying a new shroud. Does anyone have any ideas? This radiator carries the part number: D3TA-AHA, and under that it reads W MO 72 10. Thanks!

Are you sure your measurements are correct?. I ask because there aren't any radiators out there with those measurements.

If it was mine i would check auto yards , they usually ahve a list of what other years fit your 73 or i would go to a radiator rebuild shop and see what you can do?.

 

Nice truck!!!!!
Did you try any aftermarket parts chain stores? they may have what you need.
