You'd probably have to buy both and compare them to see any differences.   Are all your other parts for your cowl induction (ZL2) setup factory original to your car, down to the week date stamp on the left rear corner of the hood?   If everything is original 'except' the throttle arm pedal, then I'd really question *what happened* to the original part for your car??  it's not something that generally wears out or breaks??   If everything else is *reproduction*, then I'd buy the reproduction throttle arm as well...
