Hi BuicksChevelle! I couldn't dig up that spec on the web unfortunately. A Chilton's will probably give you that measurement or perhaos the parts guy at your local Chevy Dealer could dig up a source. I did come across what could be a good resource for you that reportedly is free ...Good Luck "There is a free packet from Chevrolet Motors that is the ultimate reference for your classic. Have your VIN number handy when contacting them for this free pack. Chevrolet Customer Assistance Center Chevrolet Motor Division General Motors Corporation P O Box 7047 Troy, Michigan 48007-7047 Phone: 800/222-1020 Don't be surprised is it takes 10-15 calls to finally get through.

Better hurry, just a day left in the bidding!
