Ken,

You certainly have provided a lot of data to digest.  On thing, though; what
are the Btu/hr ratings of the two choices?  I am not sure if this has any
statistical significance or not, but I have had 4 vans 1 with a Cu radiator
and 3 with Al radiators.  The Cu radiator expired (terminally rotted out) at
less than 90Kmi.  The Al radiators all have lasted over 140Kmi so far with
one having 208 Kmi on it and, the last I heard, still going strong.

Also, removing the manufacturer's trademark name is usually done to second
quality merchandise.
