Ron davis got back to me and he quoted $770. For half that price
you can buy two new cores and have a welder weld it up.
Heck you can buy an all aluminum NASCAR rad for under
$200 from Summit or Jeggs. No thanks Ron Davis.
Time to practice my tig welding on some junk rads

I doubt the performance increase is worth the effort, but if you really want
one, why not order a Griffin two row radiator without any outlets installed.
Cut a slot the length of one tank, and install a baffle of 6061 to separate
the rows of tubes. TIG the baffle into place and install outlets anywhere you
want them. Lynn E. Hanover.
The proplem with that is the heat conduction path provided by the fins
between front and back row tubes negates the counter cross flow design.
The space between front and back sections is the subtle key to effective counter
cross flow radiators. On the other hand two stock one row cores would work fine
welded back to back. Most new cars now have large area one row cores.
