A website visitor named Jack is looking for information on the little-known Heavy Duty Suspension option for his 1969 GTO. He has sent in photos of the air shock setup that came on his 1969 GTO when he bought it in 1988. Jack is looking for the part number and if possible a photo of the original rear Heavy Duty shocks. If you have photos of yours, please upload them via the Self-Upload link on the main menu. These look just like the aftermarket shocks on my first car, a '68 LeMans.
