Hey all ! Completely new to the Stang world. I bought a 68 Mustang Convertible for my parents for their 50th anniversary. My father is a retired Ford man, and we’re a Ford family. I have very limited knowledge of cars. i really need help on how to correctly identify and confirm the motor is a J-Code. The VIN has a J in it. Also, where’s the best source to estimate value of the vehicle? Condition between fair to good. Thanks in advance! Joe.
