I've had a heck of a time trying to get a complete harmonic balance for the project '93 I've been working on. I have an "experienced" H.B. I just got through the forum, with the 4 bosses on the back side for the crank position sensor, but with none of the vanes on it for the wheatstone bridge crank position sensor pickup to read. I haven't combed out the shop manual for what they look like or are built to, but can't imagine it's in there from what I've already seen. Can anyone let me know what they look like or are made from; dimensions and such would help. If someone's got a picture of what they look like, I can fab some, but I need an idea of where to start. Once I get the front end all assembled I can build the triggers from looking at where the sensor indexes to the balance. But, if I could see what a running unit looks like, it would be one less problem to solve when it doesn't start initially. There's not a lot of examples to look at around this neck of the woods. I'd appreciate any help here I can get!
