700R4 Speedometer Gear Change
I have an 88 GTA with 700R4 and Borg Warner 9 Bolt 3.27 (GW6 code). I just rebuilt the rear end and changed gears to 3.70. Does any one know what size speedo gear I need to calibrate my speedometer with the new gears. Tire size is 255/50 16R. Thanks

You need to know what speedometer gears are in the tanny now then use the speedo calculator in this site and order gears. http://www.transmissioncenter.net/sp...__va.htm#700r4
