i had access to some wheel locks for these type of lugnuts. the problem is the vendors will only sell them in sets of four of the same kind. since most two-wheel drive vanagons and westies use bolts up front and nuts  in the back, that means you have to buy a separate set for the front and a totally different type for the rear. in other words, you have t buy a set for vehicles which use bolts and a second set for vehicles which use lugnuts.
