As Seen on eBay

I guess it would be the same as a factory posi in a 340 Duster;-)
or otherwise known as a sure grip.

I gotta tell you that this argument gets old with me.

So what do you call a Spicer "limited slip", allowing that they were used in just about every brand of U.S. made car or truck, and some industrial stuff?

Do we HAVE to use a different term because this here Spicer is under a Ford, that one there is under a Jeep, etc?
