umm pics? and are they infiniti j30 axles or 300zx ones....
"You can also get a VLSD200 from a
non-turbo Z32 (90-96) 300ZX, but it has different output yokes and you will need axles from a 1991-1994
Infiniti J30 to match it. Those axles bolt-on to the 240SX with the non-turbo Z32 diff. Turbo Z32s have a 220mm ring gear and the differential will not fit. "
