This looks great. Now all we need to do is find
out where we can buy them. I am working on that.

I've been AFK for a few days, or would have come in on this sooner.

Back in my misspent youth, I worked for a division of Chromalloy.  We
made radiators, cores and custom heat exchangers -- for a while, we were
THE source for new exchangers for your P-51 or P-38, not to mention
radiators for various antique cars.

Radiators are SIMPLE.  They are just a way of bringing coolant and
airflow as close together as possible while still keeping them apart.

They are primarily of two types:  crossflow and vertical flow.  The
advantage of vertical flow is that sediment and other solids falls down
into the bottom tank.  The advantage of crossflow is that you can make a
radiator that goes all the way across the front of the car.

There is a third type of common automotive heat exchanger, not generally
considered a radiator but that's what it is anyhow -- or, more
precisely, a radiator is just a subgroup of heat exchangers -- and that
is commonly known as a "heater core."

Yep, that's right, the forgotten little "radiator" under the dash.  It
is just as strong as the big radiator that won't fit into your airplane,
and they are available in a bunch of sizes and configurations.

Go find your friendly, neighborhood radiator shop, the kind that has
been there so long the wooden structure is starting to petrify.  Take a
look at the book they order replacement cores from.  They have long and
short, rectangular and square cores, even some which are essentially a
cube.  The tanks and tubes go every which way, and if you can't find
exactly what you like, they can take a bare core and build it into
whatever you need, and probably supply the header tank as well.  If you
get the guy interested in the project, he'll grab that ball and run,
because it's not just another Chevy!

So have some idea what you are after, but still have an open mind when
you go see them, because they are the parts experts.  The guy at the
auto shop counter only knows how to get the box the computer told him to
get, the radiator shop guy can tell you why the one from the '65 Mustang
is better than the one from the '67 Mustang (or vice versa).
