Manual disc brakes vs power disc brakes questions

Either will work fine. Looks like you figured out that the V-L line is A-bodies. It's just the codes the used in the factory manual.

The B-J-R-W line includes Challengers, and it shows the manual disk m/c at 1". Mines 15/16" and is no where near bottoming out on the floor on my Challenger, even with the 2.75" bore calipers. So, you can use either a 15/16" or 1-1/32" m/c, it will just be down to what you prefer as far as pedal feel.
