That one is the Lee kit. Trumpeter also did the car in both closed roof and an open top so the official could stand and wave to the proletariat as he rode by. Trumpeter's version is very much the same but had separate chrome exhaust. I have both, also the Lee kit. I built one of the Trumpeter kits and used some suspension pieces from a 1/20th scale S10 from Lindberg and used an engine from the Otaki Thunderbird with the Ford lettering filed off. The CA770 engine was cribbed from a Dodge 318 early style engine, very similar in design. I believe the Lee kit was a copy of the Trumpeter but there are some differences.
