My differential **** the bed! So now im replacing my old stock 3.23 gears with 3.73! What size is my ring gear? I have no clue! I want to make sure I order the right gears before I do anything! Thanks!

if you have the 10 bolt rear the ring gear is 7 1/2 or 7 5/8. they interchange. actually i think all you can buy are 7 1/2 gears.
