Lots of forklift trucks over the years have used car engines lpg and diesel.
Just take the starter to a autopart store or car electric repair workshop.

a car with a hyster part in it? that's odd, but then again sometimes these parts might interchange. As for the model? any model that has the same mfg engine would most likely have this same starter. What would be more helpful is what engine does it have in it?
But if it were me i would just get the correct oem starter from the autoparts store or car dealer based on the model of the car and what engine it has in it.
honestly i'd be willing to bet the hyster part might be more expensive anyway than the dealer or autopart store price. You never can tell these days though.
