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.

 
Thanks for the info Lynn.  634 is a standard size.  The 6 means that it's a series 6, which in some way designates the width.  34 is the number of rows.  The info that I've seen on the coolers shows that they all have a common female thread, and you screw in whichever adapter you need for your hoses.  Perhaps they offer some common adapters pre-installed, and just work it into the part number. 
 
I'm a little depressed to find out that they're so big.  I recall that you said you could likely make it work with two, but that's still a lot of cooling area.  I'm guessing that you've had occasion to try stock Mazda coolers at some point.  If so, how to they compare to these Setrabs?  I'm probably going to just order the 650, which is the same width as yours, but with 50 rows, bringing the length to 15.25" without the fittings.  I can only hope I don't need two, because it's $345 :-0
 
Thanks again for all the info.
