i have been looking on the internet for new suregrips for an 8 1/4 and i found alot of places are offering a 742 case (i think) cause it has clutches from mopar perforance? and most are offering them for $313 with out gears. are there other cases for an 8 1/4 or is 742 the only one. cause while the rear is out of the car we want to replace the diff,bearings,and anything else needing to be done in the rear. are there any recommendations for bearings and stuff like that?

thanks craig jr
