I purchased this tach in the mid 70's. It was for a mag ignition so I never used it. It moved with me over the years and last year I found an 8 cyl sending unit for it. Sometime in the 40 years the rubber for the mounting ring melted and made a mess in the box. Black sticky stuff all over. I am asking $450 obo for everything. The NOS sending unit was $100 last year.
This tach has never been used.
Thanks,
Steve
