***get heavy-duty double sided tape***
i had the same problem with my atx pedals. i know this might sound like i went the ghetto route but i found a set for $20 at pepboys and i took them apart to paint them and everything was cool, so after they were dry i went to put them in the car and they didnt fit at all. i was so mad. i got the brake pedal on pretty good but the gas pedal didnt wanna go on at all, so i went to home depot and got some heavy-duty double sided tape and put it between the stock pedal and the new pedal and they've now been on the car for a year with no problems. i hope this helps you out.
