Re: calibrating speedo for t5 swap.
The 95 probably has a 17 tooth reluctor which is 17 pulse per driveline revolution.
The third gen had ~4004 pulse per mile signal which is a lot less PPM than the 95.
But, they're the same type of signal. So using the Dakota as a reducer in between the 95 VSS and the 91 VSS buffer box (which splits signal to the ECM, Speedo and cruise) should be all you need to do.
