So you don’t know. Transmission tunnels and crossmembers should all be the same. They all housed the same transmissions. All the same dimensions from motor mounts to engine mounts. Similar firewall locations.
Please don’t answer if you don’t actually know. Been working on Mopar for 35 Years and can’t see why there would be a difference. Holley may not know 100% because they fitted it for a B body and don’t want to say until they actually fit it to an A body.
