Compomotive finally got back to me, seems this rim is no longer made, so looks like a used hunt is on.
As an aside, in this day an age why is it that companys, and im talking about the 4x4 toy shops never ever reply to email q's about things they don't have and can't sell you, there was one company i must have emailed em half a dozen times, not once did i get a reply, a simple 'this product is no longer available' would do.
