Replaced the resistor and then proceeded to burn the points in a half hour of driving...

I feel for ya bro, I had the same issue. Truck would go thru points like a kid with candy. Especialy after I did the usual tune up, had replaced plugs, points, condenser, coil, ballast resistor etc. It almost always seemed to happen on shutdown. The engine would do the dieseling dance like it wanted to shut down then when it finaly did, the key would be in the off possition, engine stopped then all I had to do was turn the key one notch to the right and bam it would fire right back up
At one point the ensuing backfire cost me a muffler and damn near a carb.
Luckily there are a few options that have been listed here already based on where you are, you may have some luck finding a later model electronic dizzy to swap with. If not, those 2 options you listed from JC Whitney may work for ya. I would find out what the return policy is on electronic parts first.
And if you have to go with the 1741 kit, it will work, just depends on your ability and tools you have to do a couple mods. The ring itself is the easiest part and there are 2 different methods for snugging it up for a perfect fit. For the module itself, I drilled off the rivets that hold it to the base and measured and rechecked, then took a small bit of plate aluminium and made my own base using a rotozip and drill press. If you have to go the 1741 route, I could probably talk you through it.
