This V-6 has a very hard to find/hard to reach CKP - it is directly under the Distributor, about 4 inches below, inwards toward the Transaxle "bell". Almost dead-center in the back of the engine.
Your going to have to take the Air Filter and the air manifold that runs to the engine off. After that, take off the horn assembly to gain very, very limited access to wedge an extended ratchet into the bowels of the engine. 
I think the same socket that undid the horn assembly fit the CKP nut. It takes 10 minutes to undo the bolt a couple ratchet clicks at a time, at least 15 to get the thing to wiggle out, probably 15 minutes to unconnect, reconnect, and snap back to the fram the wire harness, and at least another 10 minutes to ratchet the bolt back in click by click.

Now you know why they say shops charge $500 in to do this - I think they must take the entire engine out... Very painstaking job that requires patience and precision... but quite satisfying to finish it yourself. 

Good luck and hope this helps,
