Default Upper Control Arm Spacers

Fellow Vetters:

I have lost all the labels on my upper control arm spacers and don't have any idea how many go on each pivot rod mounting bolt. None of my photos show it either. So, is there a way to guesstimate the correct combined thickness of each set of spacers? I have all of them but don't know how to create a temporary setup that will be safe to drive to an alignment shop. As always, thanks in advance for your advice and assistance!

Some auto x ers say the first step is to remove all the shims so you there.
Not really, I would split them equal and tighten it up. Then take it to alignment shop. There are YouTube videos of DIY alignment with a digital level and string; if you want try to get alignment close.

I had 1 on the driver's front, 2 on the back.

Passenger front: 5 and 1 thin, back same.

Hope that helps.
