I am working on a project which involves a 3800 V6 being used in a custom trike application for a handicapped individual. The owner has already disposed of the car, minus the engine, tranny, subframe, wiring and ECM. The owner "believes" it came from a 1989 Pontiac Bonneville, however I would like to be sure before continuing with the project. How can I determine what make/model and year these components came from? The Engine ID below the water pump is 2JW304474.
Any help you can provide is greatly appreciated.
