There were no column-shift Mustangs.
My father and I restored a 64.5 Mustang. It was a V8 (think it was a 287 c.i or 289 c.i). Unusual thing about it was the factory bench seats and a factory add-on a/c. It was an automatic with a floor shift.
You're right, of course. It had 3 on the floor.
I was confusing it with the car I learned to drive in just before I got the Mustang, my parents '63 Chevy.
I bought the Mustang with earnings from my very first job, for only $350. It was cheap because the previous owner had blown the engine, replaced it with a Falcon engine, and got tired of working on it.
I kept the Mustang from '72 - '78, very reliable. I traded it in for a more sporty car, a 1972 Opel GT.
I had one.
