I bought a 89 truck with a rear 2500 6 lug 14 bolt sf 3.73 gear recently installed but I want to know what I need to do or which gear do I need to install for the gears to be the same infront

You don't need a new differential. Unless it's somehow destroyed. If it's working fine, you need to get a new ring and pinion set. And as already mentioned, seals and gaskets.The same differential just need regear the gears to 3.73 ? Or do I need a new differential
This X2. Probably way less work as well.Much cheaper to just get a junkyard diff with 3.73s already inside. It's a common ratio, shouldn't be difficult to track down.
