I managed to secure a set of rear spring single leaf cushion pads from a member over on the SuperCar site. 2 sets of part #3792585 & 3791381 in the original GM box. I, for some reason, had never even tried to source these but when I saw them up for sale, I thought I better buy those. I'm glad I did as I learned something I never knew before. Both the top and the bottom pads each have "Forward to Increase" & "Forward to Decrease" molded into the rubber on opposite ends, along with an accompanying "+" or "-" . If I stack the 2 appropriate halves as they would be installed, it is obvious that the line of meeting slopes up or down slightly from one end to the other. One has to make sure that the 2 halves are properly orientated to each other at installation or the gap at the ends will either be too tight or too wide. Can someone tell me how to dtermine which way is correct for a car? I will also report that it looks like when you went to purchase these, you ordered a complete set of 2 halves for each side to do the entire car and so since it was a combination of 2 part #'s, the order itself was its own part # under "1 #3921060 G.R. 7.545 Cushion Unit" I likely may also post this on the SuperCar site.
Thank you for any and all help
