Just purchased a diff for my Duster

I agree with @Icetech Take a real good look at those bearings before tossing them. The seals are easy to replace, and you will need to do them. If you put it together with the old bearings, after determining they were OK, you really haven't lost much. The axles are pretty easy to remove.

Meh, you just agree with him cause you like his avatar. lol

O.k. Went back to the seller and bought the 3.91 pumpkin as well. It isn't a sure grip like the 3.23, but it can be converted I'm told. Housing, axles and the 2 pumpkins all for $1,000 CDN. (around $700 USD.) very happy with the purchase. Bonus! The lf. rear quarte rpanel arrived today as well!

The 3.23 is a great gear. I think the 3.55 is the gayest gear on the planet. The 3.55 is too much gear for a lot of highway driving and it's not enough for a performance car for the track. The 3.23 can actually do both respectably as long as you have enough horsepower. I'd skip right over the 3.55 every time and if If I bought a rear axle with a 3.55, I'd change it for something else.

Mostly agree, but on my 67 Barracuda, I went from 3.23 gears with 26 inch tall tires to 3.55 gears and 28 inch tall tires. Works out to be about the same effective ratio (28 divided by 26 times 3.23).
