I am going to be going through a 8 3/4 rear to put in my 69 Bee. I am going from a 4.56 behind my low 13 second at altitude 383 4 spd car, to a 3.91 and a 500 stroker by spring. I have everthing to do it ( new Detroit Tru Track, bearings, ordering a Dr. Diff yoke) and was wondering if these caps and spanners might be in my best interest while its apart ? I don't have the money to go Dana and would like this to hold up. In all honesty it will see may ten to fifteen passes a year.


If you hook it good at the track with slicks, it will break someday but it will take a while.
The ring gear (or pinion, or both) will develop cracks and eventually break. If you don't hook it hard, and mostly street drive it then it's not as bad....after saying all that I agree the Dana 60 is the best and really should be what you use. I use one in my duster and I would not use anything else personally.
