I have a 1990 B2200 and the radiator retted away at the upper hose inlet. Cheapest OEM replacement I can find is almost 200USD, so I am looking for a cheap replacement even if not OEM, just wanting to know if anyone else has retrofitted a radiator from any other car/brand.
I have absolutely no problem fabricating anything needed, as well I have the tools, but I am having problems cross referencing the size to any other brand, which is why I am asking if anyone else may have already used one, and what fits.

 

Everything is expensive these days....

 

Does anybody know of any interchangeable radiator for the truck? as long as the hoses are good and fits, don't mind fabricating mounts or anything

 

I would just get the all-aluminum 2-row radiator, fits both automatic and 5-speed B2200 trucks. I had to drill 4 holes to mount the 5-speed radiator shroud though (blue arrows), but the radiator itself bolted right in on my 1988.
