caliper/rotor questions...

[ChadW]

putting together a project that i bought that had a bunch of pieces with it. It is a 66 and has CPP drop spindles. I am needing to replace the rotors that came with it as they have rusted from sitting and pitted etc.. On the rotor, there is a number stamped, "PT27K9" How do i find out what rotors i need or can use? It will be a disc/drum setup. I will need to pickup calipers etc as well so i am trying to figure out what year(s)/model i need to be looking at in the parts stores...any help appreciated..
