Hey folks, First time on Forum. I need a speedometer for the FiberFab MIGI I built in 1980. The original speedometer died. Anyone have a NOS or used speedometer or any suggestions for a substitute that would work with the VW MIGI chassis? Thanks for your help.
I replaced all of my instruments, including speedometer obtained from Classic Instruments. At the time, 2011, they sold a adapter for VW, a cable that fit square home in front wheel bearing cap with electronic transducer that interfaced with speedometer.
When I did mine, about 10 years ago, I bought a used ’73 Bug Speedometer, a white-face gauge kit, and a chrome bezel, then got a Classic Instruments tach in the 5-inch size to (sort of) match. This of course snowballed into a major dashboard refurb but it ended up pretty good imho and it was a fun project.
I had the same problem with my speedometer and also the oil pressure. I replaced everything with new VDOs and utilized the cable to transducer conversion that Al mentioned. The speedometer was way too bouncy and that made the calibration inaccurate. I suspect something else was going on with my cable. I gave up and purchased the gps receiver from VDO. Rock steady, accurate and comes on almost instantly. Just a thought!
