First of all, thanks everyone who answered my question on the rotor bearing preload adjustment. That's been taken care of- the rotor is on, so I'm moving on to the next step...

Next question - I've noticed that with the set of caliper pads I got, there is a set of shims with adhesive backing on them. They came in a white plastic pouch with vague instructions advising to apply the shims to the backs of the pads w/o removing the adhesive backing and checking the alignment- afterwards the backing can be removed and the shims applied to the back of the pads. It fails to say of course WHAT this 'alignment' is, and there is no mention of this in my '69 Charger FSM for the disk brake pads (although it is referring to the K-H/Bendix calipers).

My questions are:

1) What alignment is this referring to? I've never seen something like this, even on a non-Chrysler car, and

2) Do I need to worry about using them at all?

Again- thanks for any advice!
