Just picked up a 64 GT

I thought that the door keys matched the ignition and the trunk key was seperate ? I saw a set on Ebay for $65.00 ( ignition, door, and trunk) not to long ago.

I don't know offhand, I'm used to all of mine matching, as my wagon does all, ign-doors-power tailgate.

Are they the same from 63-66?? I have found the set listed places for 66-72 but not earlier.
