Well, you have to start someplace. I had two options. I could use the original radiator and radiator support from the donor Dakota. the radiator was pretty wide, and pretty tall, and it had plastic tanks with an aluminum core, the radiator looked OK, but those type of radiators don't have a good track record for long life. Option 2: When I built my 39 Dodge, I found a radiator that fit a 54 Chevy worked well for it. It was tall, narrow on the width, and about 2" thick. A new completely aluminum radiator sounded much better then the aluminum core with plastic tanks, so I ordered a new radiator. I decided to make a new radiator support from angle iron to mount my radiator and hang the front sheet metal from, and use the rubber mounting from the Dakota.
