Barracuda disc brakes on 69 Dart

Hi all,
We have been offered a complete disc brake set up (including calipers, balljoints etc etc) from a 1967 Barracuda - Could I use this set up on my '69 Dart to convert from the drum brakes?
I know I can fit an aftermarket kit to convert but this lot has been offered to me very cheap so I thought its worth asking the forum!
Also, if I can use the Cuda brakes, what wheel PCD would they be? the small or big bolt pattern?
