I have an aod tranny in my 91 and am installing some 3.73 gears next week and have been trying to figure out the correct driven gear to get to fix the speedo, as far as I have read it says that my tranny has an 8 tooth drive gear and with 3.73 gears and a 26 inch tire I will need the 23 tooth driven gear, basically I just want to be sure that I do in fact need the 23 tooth driven gear, does any one know?
I ask because all I can find is a 23 tooth that says it is for 410's and a 7 tooth shaft.
Where can I get the correct gear?
