I've searched through the forum and couldn't find many posts on this topic to get an answer. But I'm looking to find out what was the correct adjuster screw used for the 68 Camaro. I know the adjuster nuts were different between 67 and 68, but I've seen several variants of the adjuster screw from "original" buckets compared to the new kits. The part number for 67 was 5953005 and that was the entire assembly according to the AIM. For 68 and 69 the AIM specifies part number 3921445, but I see both the variation with just the phillips head and then the variation with the phillips head and nut head, and a larger flange. I've attached some pics to also show the differences I'm finding. So bottom line, I'd just like to know what the original adjuster screw looked like for 68, or if they changed throughout the year. My car is a 2nd week July, 1968 build date. Thanks
