This is for the speedometer. Does anybody know what the gm part number is for this item and if it is still available. I'm pretty sure they used to make it but it is not listed on the TCI site. Thanks.
The # will vary depending on which rear ratio you have. Pretty sure George N. will have the answer for you. I also think much of the common ID terms I've seen here refer to colour of the gear. Each unit, based on rear ratio, was a different colour. Checked the gear drive & the driven gear. None listed with 15 teeth. Let me know what you have ( engine/& rear) & I can look up the part #s.
