I have not removed mine yet to measure, but have a couple of points. My arm has a ball at the end that snapped into the rear of my gas pedal. It is a little different design than the one pictured. Also, I do have the stop in the floor that is about 1 1/2" tall and it is what the gas pedal stops against, not the jute pad and rubber mat. I am just trying to figure out the carb and linkage. Thanks for all the help.
