I thought you said in the first post that you replaced the wires... in any case...
Possibly bad wires, but *probably* not all of them.
You now know there's no spark at the plugs, the thing to do is backtrack: can you get a spark from the wire that goes between the coil and the distributor?
And BTW, is the little button in the middle of the inside of the distributor there and is it kinda springy when you push it in with your finger? I've seen them get stuck. (I've been assuming that the spring under here is what you had lost, but I'm asking just to be clear:
... Wait a minute ...
Does this mean that if you
1) take the distributor cap off, then
2) grab the rotor with your hand, then
3) turn the rotor
A) the rotor turns?
Or does it mean
1) if you take the distributor cap off, then
3) turn the key and try to start the engine
B) the rotor turns?
If it's B), OK, it should do that. If it's A) that's not good and I'd start to wonder if the rotor is the right part (or if it's broken).
