There are different length adjuster screws. I know for a fact that I have 3" and 3-1/2".
Also some are fine thread and some are coarse thread.
You definitely have a mix of parts. No telling what you'll find in a 46 year old car.
thanks and thats good info to know. for sure with the mix of parts, makes it difficult to figure out what i have and what i am supposed to have ? The FSM comes in handy for that.
