73 up disc brake conversion. Is my caliper going to work when revesered to oposite sides?

I did put Dippy Aspen Volare calipers on my 75 Scamp for years, an they work great. I never measured the piston diameter. The F-J-M-Body pistons did look bigger. Remember if u get non A-body calipers.. Passenger goes on Driver-side. an vise-versa.
If you want to use the BIG 12 inch rotors from like a Fury, Monoco or Charger just get the caliper brackets an rotors from those cars. Its all bolt-on. [note] must be the slider type brackets.
