Cummins Willys Radiator Issues

I have been working on putting a 4BT Cummins into my 1948 CJ2A for about a year now. I am in the final stages of work and I am having problems with choosing a radiator. The problem is I cannot find a company that sells an aluminum radiator that will fit into the Jeep. My approximate dimensions I am working with is 16" tall, 18-19" wide, and 2.5-3" thick. I have a few questions that I need cleared up.

First is has anyone that has done the small block conversion into a flatfender used a radiator that is about this size?
I have determined that a smallblock chevy radiator will be sufficient in cooling the 4BT.

Second is I heard that a CJ3 A or B grill and fenders will fit onto a CJ2A tub and frame. Is there more room in the grill area of a 3A or 3B that will enable me to use a larger radiator?

If anyone knows anything that may help me out I will really appreciate it. Any leads will definitley help me in finishing up the Jeep.
