Speedometer gear for 4.88 Z/28 Camaro
When rebuilding my 68 Z/28 BV 12 bolt I put a set of 4.88’s in it just for fun. Now I have the transmission apart to freshen up and want to make the speedometer correct. I did all the math to figure out the two gears and adapter I need, but can’t find my notes.
Anyone have the quick answer on the drive and driven gear I need to find? Stock tire size. Thanks, Bill Last edited by SMS; 02-08-2020 at 12:09 AM. |

My 68 Z has factory “BX” 4:88 gears. I am not sure how many teeth the speedo gear is, but it is black. The shaft gear was not any different from other transmissions that I looked at. My car I has a factory speedo reducer. I am not sure if I was any help, please let me know if you need anything else.

Any chance you know the numbers or ratio of your reducer?
