Yes, it is an 'international' size battery, remember we all trace our heritage back to the Mondeo, designed in Europe. Just got a shipment of parts: a timing belt tensioner made in England, and an idler pulley from Luxembourg.
Sears has an international Die Hard that is $80-$90 IIRC but the cheaper option is good ol' Motorcraft (~$50). Search the forum archives for many discussions of battery options.
