Hello every body need to know if I purchased the right parts. I am building a 1984 regal limited, the rear end is original 7.5. The code on the rearend axle tube is 2AC CO61 2. I ordered a 7.5 7 5/8" 3.73 gears and 28 spline posi. The posi is supposed to be out of a S-10, Camaro, or Typhoon. I also brought axles for a GN 28 spline Jegs P/N 718-A102810. Does any body know if I went the right way in ordering these parts. Thanks for the help. Just getting started. Smitty
