Apologies if i am duplicating a prior post but this may be useful.
About 6/7 inches up the pedal you will find it comes close to contacting a metal plate with a handy hole in it. Slacken the cable off to free the pedal and put a coach bolt thru the hole so that the head will contact the pedal then adjust the pedal position to suit. I found a pack of 3" x 3/8" nuts and bolts in focus for £2.99 that did the job most excellently.
