Regarding your frame drawing in post #1 above, number 1 is at the left between the B and C indications. It is the one exposed at the bottom of the cowl when the fenders are removed. The mounts follow toward the rear with 2 being opposite the C and go all the way back with 6 and 7 at the rear in the trunk with the F centered between them. Hardtop styles usually have one extra outrigger so 4 1/2 would be on a hardtop and convertible. Longer wheel base models are not covered in the drawing.


Inner would be the holes above the frame and outer is at the end of the outriggers. On the parts list page you posted above you are only interested in the 2672 models which is the 300 sedan or Cavalier model. The 4 outer listings you need are at the bottom of that page and the 4 inner listings are on the following page in the manual.. The 11 listings toward the top of the page starting 22xx are for the hard rubber composition belting like material which was used in most models prior to 51. Instead of rubber, convertibles usually had mostly solid steel blocks needed to provide the body rigidity.

It looks like only the two rubber numbers, 422328 and 437004 are used but the combinations are different depending on location. Shims and steel items are listed starting on page 333. Some of the steel spacer lengths are listed and if shims are needed they only have an X for quantity undetermined since it depended on body fit. Those came in a couple of thicknesses.

In the Steele photo in post #6 422328 is the thicker 1/2 cushion shown as the upper item, 437004 is the thinner 5/16 cushion..
