Rubber Clutch/Brake Pedal Bumpers

[eric8]

Hey guys. I'm positive that the clutch pedal is supposed to have a rubber bumper (stopper) for it that installs in the square hole located in the metal piece under the steering column. What I am wondering is if the brake pedal is supposed to have one too? The reason I ask is because my one owner, low mileage, 72 C10 automatic does not have one installed. This is a super clean, all original truck so I would think if it had one from the factory it would still be there. Also, all of the aftermarket parts catalogs I've looked at only list an application for the clutch pedal bumper. Anyone know for sure? And if so, are both bumpers the same part #?
