  1. Need rearend (?) opinions

    Transmission & Drive line
    My 85 has a 7.5 non posi rear end. The drive shaft length has been changed to fit the LS/4L60e setup. I was going to just upgrade the 7.5 to a 3.42 posi and let it go at that. I'm an old guy and won't be doing any racing/slicks/big tires and so on. Probably just go back with original equipment...

  6. Posi Carrier (& gears would be nice) Wanted

    Wanted Items
    I'm looking for an inexpensive posi/limited-slip carrier for my car for the budget car-building race I'm working on it for. I'd ideally like one with a good 3.XX gear & pinion, but just the carrier would work. Would definitely prefer a 3-series carrier. It's a normal 7.5" 10-bolt 26-spline rear...

  10. What to do for a rear end with the LT1\4L60E combo

    Transmission & Drive line
    So, now I am somewhat confused. I understand the general workings of a rearend, but I have never been inside one myself. I have never heard reference to "2 series" and "3 series" before. Does this reference the approximate break between the 2._ _ ratios and the 3._ _ ratios, as they came from...
