FYI, I have just installed a Pertronix pointless distributor system 1162A with a Pertronix Flamethrower coil 40511. Called Bosch to make sure the FST8050 retro tach would work with it. They said tach needs a 5 volt square wave on neg. Called Pertronix and they said it puts out a modified square wave. Bottom line, will not work but I could try.

Was looking forward to installing a tach in my dash, looks like I will have to make room for someone else on your list, unless someone has a solution.
