Hot HeapThe engine helps hold the US car together
Hot Heap’s engine is more than an exposed detail on the US casting: it also forms the front fastening point. The Hong Kong car is assembled differently, so the underside and engine need to be considered together.

Metal engine or plastic insert
The 1968 Hot Heap was made in the United States and Hong Kong. The US engine is metal and fastens the front of the body to the base. The Hong Kong engine is a plastic insert held between those parts; that version uses a different front attachment arrangement.
Compare an underside photograph with the engine view. A different number of visible fastening points does not automatically mean a car has been drilled or rebuilt.
The cockpit and pipes also differ
US glazing is clear and the steering wheel is molded into the dashboard. Hong Kong glazing is blue and the steering wheel is a separate part. Interior colors vary, so record the cabin rather than assuming every light interior is the same shade.
US exhaust revisions range from straighter pipes to more curved ones. Bent damage and an original tooling revision are different possibilities; compare the shape on both sides before choosing an explanation.
Leave the windshield as found
Forward-tilted US windshields are documented. A tilted screen still needs inspection for damage, but it should not be straightened with heat or pressure merely to match another example.
Check the radiator, engine and pipe ends for chips or glue. The open body makes these parts easy to see and easy to catch when handling the car.
