I've rounded up a Pontiac jack for my 68 Bird. However, I went to a cruise last night and we had a discussion about the correct color for the base and the bumper hook part of the jack. My buddy with the 68 GTO (orig owner w/22k miles) showed me his jack and it is a medium blue much like a Ford engine blue.
It was my understanding that the jacks for our FGF cars were more like the earlier Pontiac engine blue, kinda like a baby blue. I've got this thing all blasted and primed ready for paint but I am not sure what would be the correct color...
