Go under the car and look at the exhaust pipe coming off the manifold.
Your car does have a sensor. The sensor is screwed into the pipe and it
has wires coming off of it. Cats. do not fail, sensors do.

My guess is bulb or wire if you just bought the truck. The last owner may have failed inspection because the check engine light was on and cut the power wire or pulled the bulb hoping to fool the inspector.
Does you engine sound like it has an exhaust leak under the hood? 89 4.0 litres were NOTORIOUS for the exh manifold cracking between #5 and # 6 cylinders. If this is the case, the O2 sensor is not seeing the proper amount of exhaust, and it will send the fuel injectors a richer condition than needed.
Once disconnected from the battery the computer needs to go through a drive cycle during which it does internal testing of the sensors. Generally that only takes a trip of about twenty or so miles. The inspector probably told you one hundred just to be on the safe side. Most times, you don't need to make the trip all at once but over the period of about a week, driving normally, with a few longer trips mixed in, everything should re-set.
i think you pretty much answered your own question there. Use the '94 distributor in the other engine and make sure that all the sensors are in place, connected and all for a 94. Also check the crank position sensor. If left in place during install, they can get damaged if the flywheel hits it. (hope you matched the flywheels too...if different, it will not run.
Yes it matters to the inspector, if it's standers part or after market part that was added and not functioning. They can fail it, I had Off road light's on my truck and one did not work but it was illegal to use them on the road i still failed my inspection till i replaced the bulb.
I ended removing the light, didn't feel like driving off to replace the bulb and come back to get it inspected again.
Good luck and hope this helps, guess it depends on how strick the inspector is.
You could install a new catalytic converter and oxygen sensor for under $200 instead of paying someone to tell you the same thing. If you go that route, you can get cheap parts at Quadratec.com or just plain old Autozone. You just have to cut the old cat off and clamp a new one on. I did mine in about an hour. The O2 sensor is easy too. On a side note, make sure your car is drive at highway speed for around 20 minutes to ensure the cat is hot enough to properly work.
