Hi folks. After digesting the input and considering the alternatives, I got my 139 tooth stock 1955e 235 flywheel resurfaced locally. It turned out great and all that can be seen are two very fine, very shallow hairline cracks. I've been coached not to worry about those for normal (non-race) driving I will do. Along with the resurfacing, I had the ring gear flipped. It cost me $50. Notice that 139 teeth are 4 per inch.
