I bought a 1988 Sunbird with a 3.0l omc sterndrive engine that I am working on. The starter was rusted out and upon removing it I found out it was a starter for a car and not the origional starter. I have the engine model number as 302AMRGDP. When I search for the starter for this engine I get different starters and am trying out which one is the original so I can replace it....can anyone help point me in the right direction
