MY PASSENGER SIDE SHIMS JUST FELL OUT ...HAS ANYBODY MADE THE WEDGES YALL WERE TALKING ABOUT I KNOW THIS IS A OLDER POST S I THOUGHT MAYBE SOMEBODY HAD MADE SOME.

I designed a set for our car and had a machinist friend mill them out of 1/2" X 2" strap steel.  They seem to work well and my nuts have been tight every since I installed them...and I check 'em pretty regular. 
The problem is that every car is different as to what it takes to get caster.  I made the wedge that tapered from 1/2" to 5/16 and then added normal shim pack to end up with 4 degrees of caster.  It still has some uneven clamping on the shim packs but nothing like what it had when the shim packs were providing all the caster.  I would suggest you align it to have exactly what caster/camber you want and then take very accurate measurements as to the the distance the UCA shaft is from the tower at the front and back bolt.  Then have a machinist make some slotted wedges maybe 1/16" thinner but with the ratio of taper you have measured.  Then you can fine tune things with a couple of shims and it will probably stay put.
I really want to get back to the 5 degrees I had when it tried to fall apart on the way to FWB in '17.  I has never driven better than it did with that setup and had very positive return to center but I need to do a bit more noodling to make that work reliably and safely.
