Moog camber kit junk?

Hi folks.

This is a pretty straight forward question with related back ground.

I recently decided to do the front disc brake upgrade on my 67 Cuda.
I received the brake kit with the purchase of the car. Unknown supplier, but the calipers have Penstar castings on them. Most likely aftermarket upper A-arms and ball joints. Just about everything went pretty smoothly with the exception of having to torch out the original cam bolts.
I sourced the Moog camber kits locally from Orielly auto parts. Seemed like solid parts but what do I know.
While trying to do a basic alignment to enable the car to be driven to my alignment shop, the camber bolts essentially rolled right through the washer keyways and obviously are unable to be used to adjust the camber now.
Any suggestions for a supplier or brand name quality part? After doing more research, I understand that Moog quality is no longer up to par.
I only want to do this one more time. The auto parts store accused me more or less of applying too much force on them. Pretty difficult to do with a 3/4 inch hand wrench, which is all you can get in there with.
I appreciate any info available from anyone else this has happened to.
