there are 2 bolts that hold the pedal up and then you can bring it down to where you can take the pedal for it off. There is some screw/bolt/socket looking #### holding it on that i beat the hell out of to get off....and did. and the new one snaps in and you just slide that screw/bolt/socket thing back in its hole. And yes they do feel much better and took me 3 hrs to install!!
there is not how to....slip the crappy ones off....unbolt the dead pedal...its all about skills to put them fuckers on! the gas one you have 2 bolts that hold it up...pull it down and read what i put up there
