I tried posting this in my running big block thread but i need to know soon as it its and auction and its ending soon. Looking at rearends ive already come to the conclusion that its easier to get a 8 3/4. Ive been eyeing this 8 3/4 MOPAR/DODGE rearend. It is the 742 case and is a 2.76 open now this can be rebuilt into a posi with they type of gears i want. And will It work in any 8 3/4 housing. Its a ad for the center section only.
