speedo gear for 3.90 gears
 

i just installed motive 3.90 gears in my 94 gt and i love the way it feels now.but i need a speedometer gear that corrects for that ratio.where can i get this???? if this is not available what else can i do, its setting off my antilock light not to mention the speedometer is way off.

Dallas Mustang! Clicky!!

thanks for the link,found out i have to change the drive gear in the tail shaft of the tranny to get a speedo gear for that ratio to work though.the recalibrator will correct the signal to the computer and cure the abs problem but wont correct the speedometer.dont really care about speedo accuracy but the miles rack up faster when its 15-20 mph off.

Yeah, I'm waiting on my Diablo Predator to correct the speedo on mines.
