This Denso OSGR Starter Looks Like the 17570 Used on Earlier Caravan's, etc., as the Ignition Terminal is Pointing Forward, and Appears to Be the the Same Type as the 17465, Rather Than the Type Used on the 17784. The Battery Insulator Used on This Unit Looks Like the One Used on the 17784 (Rather Than the One Used on the 17465).
The 17912 Differs From the 17893 in That the 17912 Has a Battery Extension Attached to the Battery Stud of the Starter Which Then Terminates in a Battery Stud Pointing Outwards Approx. 1" Behind the CE Cover and the Ignition Terminal is Pointing Outwards. The 17893 Does Not Use the Battery Extension and the Ignition Terminal Points Forwards (In the Same Spot on the Case).
