In the process of installing Aerospace 2-piston on the front of our '67 E/SA Camaro atm. There was some minor rotor/caliper body clearance issues where we had to use a file to remedy. Seems the adage "you get what you pay for" does not mean much anymore.
Next weekend will bring the install of a 4-piston Aerospace system on the rear. We will be using a Strange master cylinder with a 1.032 bore as recommended by Aerospace...time will tell if that was the correct advice.
Sorry I can't be of more help on the subject as we are still in process. I did use Aerospace in the late nineties on a '69 B/SA Camaro without issues which is why I chose them this go around.
