Specific measurements needed for S13 FRONT ball joint

[KnifeForkDriver]

I am trying to find info on the S13 front ball joint. I need exact measurements of both the diameter of the base (the part that gets pressed into the LCA) and I need to know the height from the lower lip to where the snap ring attaches. Please refer to the linked photo for clarification. If you don't have a ball joint to measure, I could also go by the measurements of the bore on the LCA itself. Thanks in advance.

Are you replacing the ball joints? For a little bit more than the cost of two new ball joints, you can get brand new LCAs with the ball joints already pressed in.

They are for another application. I just need to verify the size. Thanks for the suggestion though.
