8 1/4 rear end 2.45 gears!

That's a good chart, but it exaggerates how oval the 8 1/4 cover is. It is really more round than that.

Oh and SURE GRIP is the Mopar term for a limited slip. Posi is a chebbie term.

Also, if you buy one used, don't jump on the first one you see. There's a gear split in those carriers and if you get the wrong one, that 2.45 and I think 2.94 will be all you can run on it. I think the split is at 3.23 and up, I cannot remember for sure. I do know there's a "2" series carrier and a "3" series carrier and they are NOT interchangeable.
