The driver's door on my 70 Barracuda won't open from the outside handle. The door opens fine from the inside. I tried opening the door from the outside and watched the linkage attached to the handle. Everything seems to be moving. I noticed that some of the plastic clips that hold the rod to the handle and the lock mechanism, have beed replaced.I tried adjusting the striker, no change. I have had the car for only a few months. I have no idea what the problem is. Thanks
