    Came very close to switching from 3.73's to 3.08's on my TH350 for interstate...then i realized the need for towing so i stuck with the 3.73's

    In your case unless you really have the money to pay someone or a shop to regear your axle just find a compatable axle for your truck with the right gearing at a junkyard and do a swap-a-roo --by far the easiest and cheapest way--
