If they are aluminim, only have a starter mount on the drivers side, & have a large oval shaped area that is open on the bottom side of the bellhousing, both are 1963 Tempest bellhousings. The large oval area is where the torque tube housing attaches to the bellhousing

The only other 54xxxx casting number aluminum bellhousing I know of is the 547975. It's near identical to the dual starter pocket 9785581 '65-70's Pontiac V8 (& Buick & Olds V8) bellhousing. Have personally removed 547975 casting bellhousings out of original late production '72 & 73 model Pontiac A & F-body's. Have not disassembled enough original 74's with manual transmissions to see if the trend continued.
