The replacement 1,275cc inline-four was overhauled by Toy Shop Restorations, and features twin SU carburetors and a mild camshaft.
Maintenance included adjusting the carburetors, performing a tune-up, and installing a replacement generator, regulator, fuel filter, coolant hoses, and spark plugs.
Power is transferred to the rear wheels through a replacement “ribcase” four-speed manual transmission also installed by Toy Shop Restorations.
Lap belts have been added for both occupants, and additional amenities include a carpeted rear parcel shelf, a heater, and a chrome passenger grab handle.
A two-spoke steering wheel frames a Smiths tachometer, a 100-mph Jaeger speedometer, and auxiliary gauges.
The five-digit odometer shows under 63k miles, though total mileage is unknown.
