The plate gets threaded on until it bottoms out.

Then the gauge gets stuck on...

You have to "level it" using the bubble on the outer edge.

Next, you look at the outer bubbles to see where the camber is.

Holy crap...I'm at 2 degrees of NEGATIVE camber??
My goal is for 1 degree NEGative camber and as much caster as I can get. The offset UCA bushings as installed will get the most caster possible with stock upper control arms but sometimes the camber can be a variable. Here is the caster number that I got:

6 1/2 degrees of caster? That is great! The problem is, the camber is too negative. By taking some negative camber out, it means losing some of the caster. Remember, I set the front alignment cam OUT and the rear cam IN. If both cams are OUT toward the fender, the camber goes positive. If both go IN, the camber goes negative. Getting the numbers you want can be an exercise in compromise where you settle for what you can get. In the end, I was able to get 1 degree negative camber and 6 degrees of positive caster.
On the right side, I had the opposite problem with camber. I could get just shy of 6 degrees of caster but that was at ZERO camber. Trying to get into negative camber resulted in losing caster.
The fix?

Mopar guru Andy Finkbeiner has those "shims" that get placed between the lower ball joint and steering knuckle (As seen above) I just took some washers I bought and used them like so:

This tilts the bottom of the steering knuckle out by a slight amount. The "shims" from Andy were listed to be 2 degrees and look to be about 3/16" thick. The washers I used were 1/8". I used these in my Charger and (along with QA-1 upper control arms) was able to get 8 degrees of caster and 1 degree of negative camber. I won't get that amount of caster with this car but the camber should come into that range.

I used these washers….

My best guess is that these are 3/32”.
You can see them peeking out from between the knuckle and lower ball joint.

Here is what difference they made.

These alone made a 1/2 degree of negative camber to arrive at 3/4 degree, not a bad number. The caster reading is obtained on the right by turning the wheel to the right by 20 degrees.

Twenty degrees is the angle at the end of the gauge.

View attachment 1716295172

You simply turn the wheel until the angled edge is parallel with the side of the car. Get as close to that angle as you can, then ZERO the CASTER bubble by turning the knob on the middle gauge.

View attachment 1716295175

Once the gauge is zeroed, turn the wheel to the left until the angle on the edge of the other side of the gauge lines up parallel the the car. That is 20 degrees off center for a total sweep of 40 degrees from when you zeroed the gauge. This was my number.

That is approximately 5 3/8 degrees of caster. That is pretty dang good. With this, I can dial back the left side to match the right. I had to do similar things to my red Charger to obtain equal numbers.
