8 3/4 rearend rebuild

Is this a drag car only? If this is a street car I would recommend a sure grip not the spool.

I would read as much as you can, and then have at it. They aren't too difficult to do. You would need a couple of specialty tools, dial indicator and a rotational torque wrench is recommended ( I didn't use one cause I don't have one) and mine is OK.

The part that took the most time for me was setting up the pinion depth and getting the pattern right, other than that it was a breeze.

What center section do you have?

741, 742, 489?
