Lock differences single key cars - exterior door lock
 

Please look at the pictures. I have some door handles that I _probably_ got from a Fintail. They almost always have a slightly concave area where the key goes into the lock. But then I have this other set that has a slightly convex area where the key goes into the lock. Ideas? Second question - Most of the locks I have have a striker that is sort of V-shaped. But one set of locks I have has a striker that is sort of opposite ends kind of thing. See pics on second post. Any ideas about which is for which cars/years?

Different striker
 

And here are the pics of the two different style strikers...
