I just thought I would post the part number of the Mopar sender that I used for my electronic speedometer. It is 1-05252438. This unit is a 2 wire type and I used it with a VDO speedometer. This unit threaded right on the old 727 and gave me 8327 pulses per mile (40 tooth gear, 3.91 gear & 26.7" tires). I can help with any connection info that anyone might need.
