difference between VSS part numbers
i need a new vehicle speed sensor. i see that there are 2 options for 1991 700r4. they are both for electric speedometers. part numbers 10456088 and 10456089. the speedo gears i am using are 15 drive and 43 driven.

Re: difference between VSS part numbers
Someone else should verify, but my understanding is the 6088 is for 3X tooth driven gear and the 6089 is for 4X tooth driven gear. I hope so, because I purchased a 6089 so I can install a 44-tooth driven gear to correct for my 2.73 to 3.23 rear gear swap.
