Not sure which case style it is? I do know that The 2 bolt holes for mounting alternator are 5-1/2" apart on center. These wells that the bolts go through are exactly 2" deep. The port where the rectangular style plug normally connects is sealed off from the factory so its just a one wire alternator. there is a single post on back for 8 or 10 gauge charge wire. This Alternator is brand new.
