Monty,
According to the dimensions given, it appears to be sligltly smaller than mine (no jokes guys).  I'll have to measure it, but I would guess that my cooler is approx. 5 x 6 x 16-18.  It has AN-12 oil fittings and something like 3/4 npt water fittings.  My water fittings are located where the oil fittings are on the one you referenced.  Both oil fittings are on the same end on mine.   I'll try to remember to take some measurements tomorrow.
