8-3/4 rear

68 cuda

mine is actually a 741 case, I had a typo in the original post plus when i got it pulled out and checked it is actually a 2.94 gear and has the cone style suregrip unit. So I don't really think your going to be interested in trading for mine. I am planning to swap the suregrip unit into a 489 case I have coming from a friend and installing the 3.55 gears I have in the garage now.
