Couple of questions for ya'll. Do the halfshaft's/Driveshaft from a 79 280zx fit a 77 280Z?? I'm getting a nasty grumbling/ click click/whine under normal speeds, under acceleration, or deceleration (or downshifting) it goes away, but during normal driving, it is REALLY loud. What I plan on doing is parts replacement/upgrade. I'm putting in the 5 speed, the diff, and the driveshaft and halfshafts from a ZX (OR so I hope!) I know the tranny is a direct bolt up, along with the differential, but the rest I'm not sure about... Any tips/tricks/advice ya'll want to throw my way, PLEASE DO!
