spring between plastic pedal and metal?
Try junk yards.
Pedal and spring is same on many GM cars/trucks, The plastic "bearing" to mount to firewall too on cars uses metal rods. Others w/ stamped metal may or not use same pedal w/ different springs.
Look for pedal holes w/o being worn out or have oil on it. Oil/grease holds dirt and wears faster.
Get whole thing and switch at home. Carefully remove the "clip" w/o damage to plastic. Get new "clips" at many parts/hardware stores.
Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
