Drive/driven gear question
Quick question guys. 85 Camaro with 700R4 and 3.42 rear, 245/50/16
I am getting two different sizes of combonation gears I need from different sites versus doing my own calculations.
Previous owner swapped rear ends, so speedo is off.
Can someone please assist me with the proper gears I need to make my speedometer accurate?

Re: Drive/driven gear question
I'm guessing the tires are 245/50/16
Im looking in my Pontiac parts book, I'm seeing
trans code /drive gear/ driven gear
85 3.42
MD8/ 15/ 41 or 42
89 3.42
MD8 / 15/ 41
MB1 / 07/ 19
The 85 also does't list 245/50/16s soo I looked at the 89s and they have the same gears listed 4 several dif sized tires..
let us know..

Corrected tire size, I misread.... sorry
