I can remember a 62 Impala with a 327/PG having a block mounted starter. As far as I know cars & trucks used the same basic blocks with auto's or stick shift. Trucks with a stick shift used a bellhousing mounted starter through 72 but the later blocks were drilled & tapped for the block mounted starter.
