You still need functioning points and condenser and rotor to get a spark. Power the coil+ directly from the battery, intermittently contact the coil - to the battery and see if there is a spark from the coil secondary cable to ground.

Bolding mine. First you need to disconnect the wire from the coil to the distributor. Jump a power wire to the + side of the coil. Then intermittently connect the other terminal to the ground, not the battery. Well, you could go to the negative post of the battery, but it is not good to create sparks anywhere near the battery. It might go boom! If you have spark, the coil is good. If not, the coil is bad. If you had spark, the points +/or condenser are bad, or the wiring is bad, or the points are miss-adjusted. Check the wire from the coil to the distributor. You are looking for any damage, especially a bare spot that is touching any metal. If any damage is found, replace this wire. Next check inside the distributor If the post through the case is touching the case, there is your problem. If any of the wires inside the distributor are damaged, replace them. Turn the engine until the points are fully closed. With the coil wires installed properly & power to it, using an insulated, (non-metal), screwdriver, pry the points open & let them close. It should throw a spark each time the points open. If it does, the points are the problem. This is the time to file the points to clean up the contacts. Also set them to the proper gap with them held as far open as they get. Turn the engine to get to this position. If this test does not throw sparks, the condenser is at least part of the problem. Replace it with a known good one. Do you have an old spare that worked fine, but got replaced just because? Otherwise installing a new condenser is similar to playing Russian roulette just not as deadly. New ones are often bad straight out of the box. One of my pet peeves is folks replacing either one of or both of the points & condenser just because "it is time". I do not do this. Points & condensers can last a very long time. I only replace them if they are bad. Before a barn fire destroyed my VW Baja four years ago, it had the same NAPA points & condenser I installed in 1978. Yes, the engine had been rebuilt at least once in that time. Keep the points lubed & set properly. Also do not leave the ignition on for a long time without the engine running. That can fry the points. Edited to correct spelling mistake.

Very true. I would say the same about spark plugs. They should last at least 30,000 miles in a Willys.

How did you make that determination? If you have an IAD4008 it is a simple mechanical device that can be repaired.

As Muley asked, how did you determine you need a new distributor??
About the only thing that can go wrong with the distributor itself to prevent spark is if the input wire gets grounded to the case, and that is an easy fix. If there is indeed something wrong with yours, it would be better to repair it than to buy one of the reproduction units. I think a lot of folks go to an Electronic ignition because they either don't know how to maintain a breaker point ignition, or they are tired of the crappy import condenser failure, but good quality points and condensers are still available from Napa, and the "Blue Streak" Standard Products sets are also good. |

Even if the bushings are bad, +/or the shaft is bent, the old one can be rebuilt. I do my own, but there are a few folks who rebuild these old distributors for a living. The last time I priced a rebuild out, it was cheaper than a new distributor. Of course it is your time & $$, so do as you want. I can be of no help on recommending a new distributor as I have not bought one in 4 decades. BTW, Pertronix & others sell the required parts/kit to "upgrade" your points distributor to electronics. They even make the kit for 6 volts systems. IHTH, Cpt Logger.

A simple Google search for “Willys Distributors” brought up this:
