4 speed conversion. Help or hurt value of car?

I am 4 speed guy I had a 73 Dart Sport 340 4 speed for 16 years and loved it! Now a 69 383-S 4 speed Barracuda. I do have a 67 383 Auto Barracuda and when taking it for a ride the habit of the left foot going for the clutch gets me in trouble as I hit the brake sometimes lol It happens quick, no harm, just a quick ops....
Kinda funny doing it....then realizing I am in the wrong car (one two pedals) Both Auto and 4 speed cars are console cars so they feel similar behind the wheel....bottom line, I like my 4 speeds!
