I have a 77 FLH with a Baker 6 into 4 that will only accept an electronic speedometer. Does anyone know of one that will fit the stock dash? Or, an aftermarket dash/electronic speedometer combo that will fit a 77 FLH tank?

A mechanical option is acceptable but it would have to slave off the right side of the front wheel.

 

Couldn't be too tough to make an 96 up softail speedo fit the stock dash...front wheel speedometer drive would be the easy way out...or you could drive it off the rear wheel.
