kelsey hayes brake swap need info

i should be getting ready to do my brake swap on my 70 swinger from the 4 wheel manual drum brakes to the kelsey hayes disc setup. I beleive i have all the parts i need form my research besides porportioning valve, master cylinder and brake lines.

First question is there any good links around for write ups with info and pics on doing the swap like 7071dartgtreg did on the 73up bbp swap?

Also i am going to do the brakes and suspension before i get the car painted. So i wasnt planning on adding the master cylinder and brake lines until i get the car back to make painting the engine bay easier. So would it cause any problems with the seals or anything to blow compressed air into the caliper to get the pistons touching the pads and pads touching the rotors? I was thinking this would be the best way without running lines and the master cylinder although thats why i am asking before i scew something up.

thanks for any info
