I bought a set of reproduction upper control arms for my 68 Charger. All of them show a washer and a spacer with the ball joint.
My originals didn't have these. Has anyone had experience with these ? is the washer and spacer for another applicatio?

Thanks

That is weird. They made the shank too long. The point of that spacer is probably to allow for the installer to place the castle nut in a position where the cotter key can reside through the notches at the top. This seems like what you’d expect on a part that has multiple applications. A manufacturer might make a part semi universal so it fits many applications. This cuts costs for them but sometimes means the part fits nothing “exactly”.
 
Did the directions come inside a Fortune Cookie ???

If those are used in a car with the front mounted 1973-76 A body calipers, the long shank will be in the way of the brake line that usually runs under it.
You could keep the arms and just replace the ball joints.
 
It maybe to control Bump steer condition on another application.

I would make sure you have the correct length joint.

You hit it with the length.. look at the thread length on this, then look at a K772 from Moog, his threaded portion is lot longer and bet the thick washer is used as a spacer, and even then there is a probably lot of length from where the castle is on the nut. If it came from where I think it came from, looks like quality control hasn't improved much in the 41 yrs since I worked in that dept..

I am not seeing the bump steer explanation. It the shaft before the taper is longer, that will affect camber gain, usually by making the spindle appear taller, changing the angle of the UCA at rest, but length of the threads means little, with or without a thread spacer. Bump steer is the least affected measurement here.
