Converting to air ride

[colc]

Having aquired Ian's rather spiffing blown '99 4motion, I'm going to have to do something about the rear ride height. I like the stance, there's several places where I get clearance problems. I have [left over from an old Yank lowrided project] a resevoir tank . pump, lines and controls. Does anyone recommend somewhere I can buy a pair of rear air struts?
