Many Interchange This With the 13249, But This Unit Does Have Some Differences. There is No Extra "Hook" on the End of the Top Mounting Ear, and the Battery Terminal and Plug are in a Slightly Different Location. The Mounting Looks Close Enough to Allow for the Interchange. The 13616 is the 90A Version of This Unit, Which Fits the Mitsubishi Galant. Mitsubishi TSB 96-16-002 (November 1996) Calls for Replacement Alternator #MD327533 (PIC 203-5041) When the Car (1994-95 Galant Models Mentioned Only) Requires a Higher Output at Lower RPM's. The TSB Also Indicates That Pulley #MD618930 (Smaller OD) Should First Be Installed on the Original Unit, Along With Replacement Belt #MD329451, To See if the Problem Can Be Corrected Without the Unit Replacement. If That Does Not Solve the Problem, Then the Unit Gets Installed.
