The top one (more rusty) is a 1969-70, the bottom is a 1965-66 and would be the right one for your car.
I'll let Charles chime in on the ratchets vs. flip style handles, but I think that the early cars had ratchets.
There are two ratchet style handles for the early cars, one with an "open" handle, which is the 1964 1/2 - 1965 cars and the 1966 handle they "rounded" or "crimped" the handle.
There are many different styles of lug wrenches, if you have one with a hole in it, it would not be correct for your car, if it has a hole, it is for Feb 67 or later because they changed the mounting the jack to be on top of the spare, and the handle was on top of the jack.
Post a pic and we can figure out what you have there.
