I bought too many D Rind Isolators and they don't work on my rear bumper. And Amazon want's me to pay the return shipping because it was my bad for over ordering so If anyone wants them I'll sell them for what I payed $11.31 each box shipped. I have 3 boxes of 2 so 6 in total. They are all black and brand new but i will remove them from the boxes to save on shipping. They will fit any 3/4" D Ring IE Shackle.
