Passon Performance 5-speed

jamie, chris the fuel guy here, what I have is a original 70 road runner, with a factory 4-spd, bottom line is the wife said if I cut the car in anyway, she will cut me,if you know what I mean, hahahaha, by the way it's a slap-stick shifter, if need be, can I transfer the arm to it.... Thanks again chris the fuel guy
