hey fart drinkers!!!
I got a complete posi-traction GU4=3.08 rear end with 86K miles, from an 88 GMC Vandura yesterday for FREE!!!
that saved me 250 buckowitz.
it's a higher gear ratio than I had (GU6=3.42) to begin with, but I think it'll save more gas, all our roads are 55mph and long so it's mostly hi-way driving around here.
Now to degrease, pressure wash, paint, and replace the seals.
