I'm trying to research a 66 Mustang convertible with what appears to be rare options.it is a 289, 2bbl and a has sport sprint decal on the air cleaner…..it is auto, has factory air, power steering, power brakes (all drum), pony interior, bucket seats with a full console, remote mirrors…….I'm not an expert but have spent allot of time with these cars…..the VIN: 6S08C163598……just wondering about the combination as well as the sport sprint decal on the air cleaner…..it all appears original……not restored……thank you for your assistance,
