You have a 7.5" rearend in that car. Your best bet is to find a complete rear rearend out of an 85-88 Monte SS, They all had 3.73 gear and many had the G80 posi. They will bolt right in and there are many of them out there. They did come in other G-body cars like T-Type/Grand National and Hurst Olds up to 83. In 84 these got 8.5" rears which are 2 to 3 times higher in price than the SS rears. Go for the Monte SS rear and it will be all you ever need, Hope this helps.
