Ok, Picked up this 8.75 axel this weekend!! It is from a duster, so I will store the axel with hopes of coming across an A-body to get on the road. It is rather interesting though, the gears are 3.91 posi, and the one wheel has reverse threaded lugs? I know I have read about cars coming from the factory this way but how rare is this?
On a side note, I am torn about weather to put the 3.91 section into the challenger or not. I am currently running 3.55 open and wondering how bad the 3.91's would be on the highway?
