I think I found a core that will work. It is a 2 row 20"wide x 21 1/2" tall x 2 1/4" thick.
This will give me 430 sq inches over the 336 sq inches I have now.
I think I will make it into a two pass radiator as well for good measure.
So if you get this that'll make one more auto manufacturer we can add to the list of donors to the Willy Mammoth. I noticed that it goes to a Ford at the bottom of the page there.
