I'm going to put a 3.73 posi in my IROC. Its like a 3.23 right now. When I put in the rear, what do I do to correct the speedometer. Keep in mind its an 85 and wont just program like new cars, has the 700R4 in it.

go to kdsperformance.com and look around there. i forget what the part name is, but it's basically a gear that goes into the tranny, looks like an easy install and they will help you with any questions you have.you can\'t get off if you don\'t get on
