Once upon a time, I came across Zack Heisey 's modest advertisement about his fresh-off-the-mill HEI-style distributor. The list of parts he put in, and amount of work to put one together, was on par with DUI's famed product, and the price - less by far. All together, it was a great reason to make a little dent in Zack's enormous outlay in his purchase of warehouse full of NOS parts.
GM parts tend to be simple, reliable, inexpensive, and easy to find. These are all the features you want in a part that goes in your Jeep. One of the great things about it is, it is extremely simple. The HEI ignition has two wires that get connected to it, one is 12v which should be hot on run. The other wire is for the tachometer.
