    All of thoes terms to me mean the same thing, The differential!! Althoe the pumkin can be just the housing for the diff to sits in and a 3rd member is in my mind like the F**ds and Toy**as that are removable as a unit from the front side of the axel it self.
    this is just the way I vew this lingo tingo stuff....

    Spider gears are used in “one-legger “ setups. Not posi or locker setups. They are a set of gears in a cage in the center of the diff that allows the axles to unhook and for one axle to spin faster than the other in a turn. Thus the term “differential” as in different speeds, Cosmo! The spiders transmit power to both axles when you are on the straight and level and applying torque through the diff to the tires.
    Carrier is the case that the ring gear is bolted to inside the third member.
    Sounds like Mr. Parts is trying to get you to buy a bunch of stuff while not making sense. Diff work needs the right tools. You ain’t gonna do it in your back yard. Contact a specialist. There are some outfits in Denver that do this stuff. You can remove the “3rd” member and take it into a shop to have it set up. Cost is usually around $250 and well worth it.
    Did that help any???
