The number on the transmission is 10N522897 - is that a 350 transmission and what was it originally installed in - trying to figure if it is a proper match for the 350 from the 70 Camaro. Since everyone at the parts houses tell me there are no other starters to fit the engine, is there a possibility that the flywheel is not the correct one and there should be one more concave that would throw the flywheel forward closer to the starter? There are no shims between the flywheel and the crank, so no slack to get there.
