To all those who insist the striker plates for my '63 are adjustable,heres some pictures that contradict that notion.(photo numbers 020,030,035,038,042,048) http://community.webshots.com/user/boondawg Photo #048 shows the backer plate that is factory riveted to the inside of the door jamb, and holds the threaded blocks the striker plate bolts to, from turning or moving.Photo #035 shows the rivets. Do you now concurr that these striker plates are non-adjustable? Boondawg
