I changed the gears in the Chevelle from 3.73 to 4.56 with 28" tall tires. I need a speedometer gear reducer. The drive gear has 8 teeth and the driven gear has 21 teeth.
Does anyone know how to figure out which one I need or have a part number. The little research I have done says I need one that's has a 20% reduction? [img]<<GRAEMLIN_URL>>/dunno.gif[/img] Thanks, Kurt

Dan </div></div> Not yet but the guy who built my trans was really close as I need about a 20% reducer. After sitting on the computer for this whole time, I know GM has a .8241 (3950352) which would get me to 2.707 and I'm currently at 2.65. I'll keep searching or buy a aftermarket one and change the driven gear on the trans if needed. And I'm NOT going to pay $236.55 for one! .8241 Adapter on eBay Kurt

I know there is a formula but how to you apply it to the gears to recalibrate the speedometer?
