Thanks for the pic.  Are you sure those are 13 row like you mentioned
 before?  According to the Setrab info, a 13 row would only be 4.75 inches
 long.  Those sure look longer than that, but of course it's hard to tell.    In my original comparison, I looked at only the amount of tube length, or
 primary cooling surface.  If you look at overall area of the cooler, the
 Mazda unit seems much larger.  The Mazda unit has a core that's 19.5 x 5 x
 2, for a volume of 195 cu in.  The 640 Setrab has a core volume of about
216
 cu in, but appears to have almost 3 times the primary cooling surface when
 you look at the number of tubes.  I think I've confused myself even more...

This just in.......All three coolers are P/N 50-634-4063. There is another number below the part number, titled "Description Number" that is 634AN12. I think that just calls out the outlet size, but may include that the cooler is a 34 row. The male outlets are AN-12.
If the top and bottom strap carry oil, it is a 34 row cooler. If not, it's a 32 row cooler.

It is 2" thick.  The body is 11 1/8" wide. It is 13" wide to the ends of the mounting flanges.
The body is 10 3/8" tall. Including the outlet fittings it is 11 1/2" tall. To the outside of a 90 degree dash 12 hose end, it is 13 1/4" tall. Lynn E. Hanover
