I can’t find my Marti book and was wondering if there is a breakdown on 4 speeds for the 390 GT engine in 1968? Trying to find out if my car had a wide or a close ratio 4 speed in it originally but all the report says is Four Speed Manual Transmission (5). I see on the David Kee Site that there were close and wide ratio transmissions with a Mustang having a 390 engine. I also remember reading on a few occasions people claiming that their cars came from the factory with the close ratio trans. Illustrated Facts book has nothing.
