Early A door and ignition locks

New Door locks for the 65 and earlier models (A, B and full size) are quite hard to find and expensive when you do. Rekeying used ones is not the easiest either as the spring cover is a press fit and and doesn't tend to stay in place after being removed. It might be easier to adapt the lock opening in the door to accept the easy to find and rekey the 66 and later locks.
