Just came back to look around and realized I never answered your question. My build date is 4-11-57 and SN is 31211. I identified my engine as a Continental. I found an old air compressor with the same engine so I trashed the military distributor setup from mine and installed the regular type with new plug wires and solved my ignition problem. I found out the master cylinder is the same as an old Ford, wheel cylinders common so I got my brakes working. I'm still in search of a service manual if I ever come across one. It's a fun old lift.
