I'm trying to change the door locks in my '69 roadrunner. I took the tiny c clip off the back of the new lock, the part inside the door, and removed that piece to get the rod back into the hole. Now I cannot get the tiny c clip back on. I can see the clip only goes on one way. I lost one clip down in the door already and I'm using my last one. Is there a simple way to do this? Should I remove the whole rod from the locking mechanism in the door also? I have a '69 Plymouth manual but it is not helpful.
