I am slowly putting together the pieces to put a 12 bolt in my malibu. I am currently running a 700R4 and will be replacing the 7.5 3.73 SS rear with a 12 bolt 3.55 setup this spring. Anyone on here running that setup that could possibly take some "accurate" driveshaft measurements? I can measure mine once its together and on the ground, but I would like to browse ebay and find a nice aluminum driveshaft instead of paying $$$$ to have one made after I have everything installed.
