Ello Frends 8) i have question for my original 12 bolts (69 Z28) ,what is the E under the diff code ?
Thank you
Because your rear end has limited slip, aka posi-traction or posi for short, the E further describes what brand of limited slip unit was installed in your housing. In your case, E is for Eaton.
Yep.
See this link and scroll down a bit.
