Looking for 8-3/4 suregrip rear for my A-body

you can pay big bucks for an abody rear,or,pay like $100.00 for a c body rear,have it narrowed for like $200.00,buy new axles for $300.00 or so,buy a center section with the gear and suregrip you want for $150.00- @ $400.00.The difference is,if you put a lot of power through the factory abody rear,the axles will break!I have broke quite a few sets of factory abody axles,there people on here that will even give them away.If your car is stock,or very mild,and you dont plant to race with it,or do any burnputs,youll proib be ok.I got lucky an found my A body 8.75 for $50.00,with 2.76 gear and single traction,but i wouldnt take $400.00 for it right now.Im sure i can find a 3.23 -3.91 sure grip for a couple hundred bucks some were,if i look hard enough,and when i brake the stock axles,ill have a set of mosers axles made for it
