Thanks Kevin for the GREAT information! Thanks go out to Mick for organizing the data for me. The MARIANNA auction paperwork yielded:
1991 FHP Mustangs - 4 total cars (all 4 had weak documentation 'til now)
1992 FHP Mustangs - 7 total cars (4 new to the Project)
1993 FHP Mustangs - 2 total cars (both are new to the Project)
As time allows (I am playing catch-up after being away), I will update the existing pages and add the new ones to the Project.
