HELP ASAP PLEASE: Re chassis/'house' dates on MH

I bought a used Pace Arrow Vision in 2000. It was advertised as a 1998 and the Indiana title and all accompanying doc matched that. When I checked the VIN for chassis it came back as a 1999. This made sense as it was a Ford V-10 and 1999 chassis year was the first year for that motor . Anyway, I bought it, when I titled it in Florida, they use the VIN, not the House build date, so my 1998 became a 1999.
