A GTX or Charger 4 spped car is super rare really as is one without AC, as you know.
Funny story. I have a Mopar bud from way back, in the 80's hard core guy, never sells anything. Well he had a 68 GTX roller original 4 speed , non AC car. I traded him a 70 V code (440-6) Cuda roller, plus I got $2000 boot. This was like about '92 or 3 maybe. Just wait, I had 4 or 5 other V code E body projects. He said later on.he had no idea how rare that 4 speed X was. I had enough of E bodies at that time and I was off them and on to the 68-70 B bodies anyway. I liked them way better. It later sold done to a guy in Ca. along with a 69 X Hemi project.
