we only use the holley stuff currently. you're right it's pricey. the pedal you use, needs to be from whatever vehicle your ECU is....many use the same one, but they aren't all interchangeable. is that the 2007 aspen? is this the one you have?

yeow...the later challenger pedal we use isn't this pricey.
