My thought would be to start a new webpage just dedicated to Nissan lockers, then visit every 4x4 website you can think of and let everyone know about it. You MUST include foreign Nissan websites(someone here must speak French, Spanish, Russian, etc to spread the word), if the demand is global and not just the US you can get their attention quicker. Have a registration feature for each person in order to quantify the numbers interested and make sure everyone knows to visit often. Not sure what content you will use other than the basics but this topic gets tossed around once in awhile on each of the Nissan boards....it's time to unite everyone.

BTW Aussie lockers are usually sold for under $250, this alone I think would drive up their sales vs. a $800+ ARB locker w/pump since the investment is less than a third. Aussie lockers can also be installed by a decent driveway mechanic so install costs would be must less as well.

Just my $.02
