78 Z differential vs. 81-83 differential?
Do the 78 280Z's use the same differential as the 81-83 280ZX's? I'm not concerned about the gearing, just the type and if a differential from an 81-83 can be a direct swap into a 78 280Z.

The later S30's had the diff moved back about 2 inches. You need the mustache bar from a '76-'78, the front cross member and mount from the R200 and the drive shaft from a '74. The R200 means a 200mm diameter ring gear. Plan on replacing the bushings with urethane. The R200 is bullet proof but I broke the mount first time I dropped the hammer hard. Check out my post on rear diff snubber, can't be broken but still isolates the vibration. Solid mounts will vibe your teeth out.
