Dont know where to...

Im looking to switch from my my stock gears on my 1995 thunderbird to some 3.73's or 4.10's but i dont know where to buy them. Where can i get ahold of these?

is it as simple as i think it is? Just drop the pumkin replace the gears,new seals and refill with new fluid?

If you can't find any used deal, just order them from Summit....look at link above.

And you can't just put gears in. You have to have gauges to set clearances.

You will almost certainly have to do some shimming to both the carrier and the pinion gear to properly adjust the backlash and pinion depth. You will need a dial indicator, depth gauge, dial indicator mount, gear marking compound, and a press to remove/install pinion bearings at the very least. If the carrier has high miles, go ahead and get new carrier bearings. I'm going with all new bearings when I rebuild my rear with some new 3.73s and TL clutches.

If you don't know how to shim a rear diff, you shouldn't do it.. it requires special tools. If you don't get it almost exactly perfect, your diff will make a goo whining noise an prematurely wear out the gears. I would see if there is a member that lives near you that knows how to do it, if not.. buy all the parts you need and take it to a good shop.
