Hi David, Maybe I can help a little as I have a "new" core just obtained
from an ebay seller.  It is a Murray #54449 and the dimensions are: overall
width, 13.5", Cooling width 10.5", depth 3.625", height 8.25".  the tank
width is about 1.375.  There are several part numbers that have the same
dimensions.  Mine has a female 3/4"NPT welded on with no problem. Rusty has
AN16 male fittings with no trouble. (correct Rusty?)
Hope this helps a little.

Ed, the dimension I'm looking for is the X (across, with "tanks" on each
side and coolant tubes horizontal), looking down from top of core, with tank
on each side - what is the left-right (X) dimension of, e.g., the top of
right tank, i.e., from left side of it where the tank and fins meet, over to
the right to the side of tank, which is curved as we look down on it, and
measure to the "wasp waist"/narrower part of the tank where the coolant
tubes runs left from.

I'm trying to find out how big a dia tube/fitting can be welded/braized onto
that plate at top or bottom of "tank".

David
