The 4 kits on my receipt are listed as "4 202-330-01-18 parts kit" at $15 each.

Labor& alignment was $190.

You might also want to check with BrianBrave. He posted:

Big Brand Tires did my alignment. (after I installed the rear camber kit from KMAC - not to difficult)

I purchased the front camber bolts from MB (In stock) for arount $20 ea. and Big Brand charged me $65 to install (1 hr shop labor) + $79 for a four wheel alignment.

About $185..

Perfect....

This makes it sound like my XF's previous owner had done the camber kit, but not the bolts.
Perhaps MB has the bolt listed in their parts catalog as "camber kit".

I'd be happy to check with Barry at Skyland Automotive if you'd like.
