I think you might be right about the "conversion" Sandra. When I checked the VIN it's 83101... where I think if I recall right fleetside should be 3103. But the engine is " numbers matching" so added bonus in my book.
I'm not looking to drive her crosscountry but there are lots of events a couple of hours away I want to check out so good to know I don' t have to be paranoid. She does sound a bit screaming at 65 70 so that's what raised my concern originally.
