Does anybody know where I can get one of these things in a hurry? I need it like yesterday and cant find my original one.

Its the pin and push clip retainer that holds the cable to the e brake pedal.

very likely you could go to Ace hardware & get a pin and an E clip of the correct dimentions that would & get you up & running ASAP with a functioning ebrake. that'd give you time to locate the correct one if desired. EDIT you can cut a groove for the clip with your needlenose pliers as needed if there's ain't the exact piece you need
