3 on the Tree shift pattern?

My first Mopar was a 3 in the tree. It was a 65 Dart 270-post with a HP273 and a 3 on the tree. I found out later it was one of only about a dozen made. Powershifting second was murder. The shifter was loose and it would get jammed in the gate. I kept a hammer under the seat so I could knock it loose from under the hood.
