How to ID radiator

Hopefully this is a simple answer, but I don't know where to turn. I have a '72 F-100, but it doesn't have the original motor, trans or radiator ... I'm running a 352, with a 3-speed auto, and it appears the radiator runs fluid through the trans too. (All installed by the previous owner). My buddy said I should have the radiator rodded out b/c it's not circulating, but I'd like to just go ahead and replace it now, assuming I can find the right one. Will this be a "wild goose chase" or will a parts store mechanic be able to tell me which one I need?

If you happen to find a parts person that knows what he is doing and can read the descriptions they should be able to figure it out. If you get one that only knows how to enter a computer, you're screwed! Greg

Measure your radiator's core, length and width (only the part with fins to get the core size), then the thickness and how many rows thick. You can see this by removing the radiator cap. Also note the location of the hoses and mounting points (bolt holes) Then find a parts store that has an illustrated catalog to match it up.
The radiator does'nt run radiator fluid (antifreeze) through the trans, transmission fluid runs through a seperate cooler inside the radiator. You could also get a radiator for a manual trans and run a seperate external trans cooler from Jegs or Summit etc.

Older radiators were plumbed to run coolant through an external transmission cooler bolted close to the transmission.
You can update it with a newer style and make longer lines.
