Not sure about the 305, but they used smaller 153 flexplates in cars and the starters were the PMGR type in 1996. Not sure when they started doing them. I stock them.
Oh, maybe it was the V6 Camaro starter then. The 4th gen Camaros just had base models with V6 and Z28s with V8s. 1992 was the last year of the 3rd gen with the rare V6 base that was usually upgraded to a 305 V8, and the Z28s which had 305s and optional 350. That was that last of the small block Chevy in the Camaro.
