1967 Dart differential question

Thanks again Fishy68, no its not the sure grip, i spin the power wheel and the other one goes opposite direction. I will have to go out tommorow and see what the ratio is.
Im thinking the rear end could have come out of anything really, the guy i got the parts car from wasnt too bright. so the fact that is a mopar rear end is something. Lol
Im actually in wash state, so not too close to him. But i appreciate the info. might go drop him a msg anyways.
I hope i never have to play with an other differential any time soon. especially the ones you mention as being true tanks. Lol
I will post what i find out tommorow about the ratio. ive got it advertised for 150 obo on craigslist.. might end up brigning that down a lil
Thanks again. very much appreciated :)
