fairlady z vlsd
 

hi guys, i'm new to the forum and i was looking at vlsd's for my s13 chuki and i noticed on ebay that the vlsd for the fairlady z is much cheaper(90+shipping) than the j30, s13, s14, s15 and the na 300z...i don't know much about differentials so i just wondering what the differences were(besides the 5 and 6 bolt axle)...i've did a search on fairlady z vlsd's and was stumped...
heres the link...

but then again they said to call for shipping quotes...
