Help

W/ this type question it always best to call local Dealer part shop and ask them. If no help there, try a local chop-shop junk yard but now they computers may not go back that far. Then u hit rock bottom. Try pubic library some have car repair alcove so you could look it up in a paper chase. Good Luck
