How much should I ask for my 1991 Mustang Clear title GT?..........Mods-Explorer 302 and GT40 heads with upgraded Trickflow springs, B-31 cam, T-56, Vortech Supercharger, AEM wideband, Autometer Boost, water temp, and oil pressure gauge, Summit aluminum radiator, electric fan, new tires, Tweecer r/t with a jacked up switch cable which only lets you have 1 setting. A/C works and heater to. Just passed emissions in January 09.................Needs-Speedometer cable, Tune, and the syncrols on 3rd and 4th are going bad and those gears grind( though I figured out how to put it in without grinding)Paint and interior are in great shape for a 18 year old car..................I found a 03 GT that Im gonna get and would rather have that one than this one.
