Thanks Tim. I kid you not---I was amazed to find a 12V square coil at the local Tractor Supply, and hoped my dream had come true. My new 12V square coil lasted about 5 hours. Before that, I was using the 6V and attempting to step 12 V down with a resistor, and was routinely burning up coils after about 100 hours. I'm tired of replacing coils.
My current thought is that the square coil was eventually phased out by Ford, because the bottom connections are akin to rubbing two wires together, so as to form an electrical connection---not a good way to do it. Position of the square coil (front mount) also means it is subject to intense vibration during operation.
I am also convinced that the modern square coil's use of epoxy resin is not allowing heat to dissipate, which results in premature failure.
I have also discovered another person who did my 12V conversion got it all wrong---it's a wonder the machine ever started!

In this segment we will finish up on our fasteners and then work with ways to keep them from loosening up in the field. Capscrews, bolts and nuts are not the only means of holding two parts together. When dealing with thinner metals like sheet tin, a long bolt and
