Quick speedo gear change? check
Quick and hopefully an easy answered question.
I have a 1991 Firbird w/ a 700 R4 transmition.
I swapped rear ends from a 2.73 to a 3.23.
Are the Grey 15 tooth drive gear and the Blue 38 tooth driven gear the correct combination to use for accurate speedometer readings?
Thanks a bunch guys,
Jim
