Questions: I have a 1952 CJ3A. it has a 124 tooth flywheel and a 8.5" clutch. The jeep has an F-head from an unknown CJ5. My flywheel and starter stripped. I don't know if it was from use/age or improper starter-flywheel combo. The starter I have is a 9 tooth bendix with PS256 stamped into starter housing. I do not have any starter id tags. I want a gear reduction 12v starter for this project. What do I need? Was this starter originally for a CJ3A or CJ5?
