280Z differential swap
I have a 76 280Z with a 3.54 R200. I recently purchased a 4.37LSD R200 from a skyline. The 4.37LSD is 0.562" longer because it has a VSS on the front snout. Also the drive flange uses 10mm bolts on a 40.5mm radius vs the stock R200s 8mm bolts on a 35mm radius. Does anyone know what car I can get a matching flange for the driveshaft from? I thought about swaping drive flanges between differentials, but I think that would mess up the pinion preload. Is this correct? I've never had a Z car diff apart.
