Sure grip 7 1/4 strenght?

Simple go buy an 8.25 rear out of an A Body (they're pretty cheap). Then go hit the junkyard for a 96 or older Jeep Grand Cherokee. Once the jeep is found pop the rear disc brake setup off and set that aside for you to buy. Pop the axles out and throw them in the Jeep. Pull the gears out of the jeeps rearend (most have 3.55 or better) and take that sure grip unit as well. Now take your new acquired gears, suregrip Unit, and rear disc brake setup and go up front pay the people and go home. Install all that stuff you just bought and install them into your A Body 8.25 rear. It's a simple bolt on/in process. You now have a much stronger rear (than the 7.25 piece of crap) with 3.55 or better gear with suregrip and rear disc brakes ready to bolt in and go! Enjoy.
