ALL SOLD Weiand 2x4 O4D for early Oldsmobile 371 and 394 may work on late 324 (1956) not sure. No cracks or breaks or repairs. Only issue I seee is a broke bolt in the front generator mount hole. Has an old polish job on it that should shine up. In some of the pics I have 2 matching Weiand 2x2 adapters mounted on it so it could be run as a 4x2 instead of 2x4. $475 shipped with the adapters or $225 shipped without the adapters
