Bringing this back to the top again.
Replaced my bushings last year when I had the frame off of my 68 Fremont build. I also discovered the same as the OP. None of the body cushions were painted or colored. but the lower cushions were all pinkish-purple. Lavender for the lack of a better description I guess.
Had the Chevrolet mount in the rear.
All the mounting bolts were 3" except for the #3 cushion under the door. It was 2 3/8".
Attached are a few photos of the original bushings. Red paint is just overspray from a previous repaint. As you can see the paint was more than a dab and looks to have been dipped.
