Radiator sizes??

[bhemingson]

I am working an a Jimmy but I think this applies to four wheel drive trucks as well. My Jimmy came with a radiator but it sits slightly above the rad support and doesn't fit the bottom support channels very well. It has some funky spaces on the upper retainers to make up for that.

Looking at parts books online I believe a 1972 Jimmy w/o A/C and a 350 and automatic came with a two row rad with the transmission cooler. A/C trucks came with three and four r? Or do I have a radiator out a newer truck because it sure doesn't fit.
