Strut rod bushings
Well, I never knew the late A body strut rods were longer and had different threads. Not too long ago, I had to replace the bent strut rods on my 65 and dug around my stash until I found some. I couldn't remember what car they had come from, but thought they were probably 73s. So now I had to go out to the garage and see if they were fine thread or coarse thread. Thank goodness they were fine thread. So they obviously were pre-73. However, they did have provision for a roll pin which my original 65s did not. I put roll pins in, and also used the two piece bushings.
