Do I need a snubber on a 8 3/4 rear end?

That's interesting.
Is that for the adjustable snubber ?

As far as I know the factory installed the standard oem snubber on autos and 4 speeds.

That's for the MP snubber. But keep in mind, Shepard is taking for granted SS springs are on the car. And he's right. the snubber isn't really needed with SS springs and an auto....though lots of people do it anyway. I have myself.
