Transmission Identification There were two basic transmissions used in the Metropolitan. For simple identication purposes they are indentifed as the long and short tranmissions. There were some differences in the long transmissions such as starter location/backing plate and the rear seal, etc. The short transmission is 21 inches in length and was only used on the 1200 cc A engine from chassis serial number E- 1001 to E-11003. It was fitted with a mechanical clutch. The long transmission is 32 in length and was used on the balance of the serial numbers. It was fitted with a hydraulic clutch.

Engine Backing Plate Identification There were two different backing plates used on the 1200 B cc and 1500 cc engines commonly referred to as the thin and thick plates. The thin plate (used locktabs) is 3/16 and the thick plate (used lock washers) is 3/8. Note the difference in the starter location. These were only used with the long transmision. Note that the engine with the thin backing plate used the early slave cylinder and the engine with the thick backing plate used the late slave cylinder as listed in our catalog.

Chassis Serial Number/Body ID Tags The chassis serial number is in two locations. One is the chassis serial number tag that is attached to the engine side firewall with two sheet metal screws. It is also stamped from the factory in the right upper shock tower in the engine compartment, on the dash to wheelhouse panel brace. This location is near the hold down tab for the distributer wiring harness. This is the offical serial number of the car as the tags can be easily switched. Note: Early 1954 cars did not have the serial number stamped in this location but did have the chassis serial number tag on the firewall. The body ID tag is pop riveted to the firewall right above the chassis serial number tag. 9
