    3.90 locker

    i was offered a rebuilt 3.90 locker, axles, housing and all for the t/a for the price of $425. Is this a waste of money? and would it wear out just as the factory unit does?

    Sweet! That is what I had in my 81 Camaro.

    Every single time I look at gears I see 3.42, 3.73, and 4.10.
