hay I read somewhere that in Canada 240sx comes with VLSD standard. I am in Canada and I just my 1990 240sx like a month ago. It has about 160,xxx miles on the transmission and differential. So I think even if my car does have VLSD it will never lock because I it's so old and needs to be drained and refilled??? can anyone confirm that?maryjane wrote:spit up the cash for a vlsd, its a direct bolt in set up and youll love it!!
