These are used Original wing support blocks that came on the 2000 Cobra R to support the deck lid where the wing mounts. These go under the deck lid and the stud passes through them and they bolt to the spoiler to sandwich the deck lid and make it more secure/stable. Obviously these are not available. This is the only pair we have and we have it because we repaired a tornado Damaged R model over a decade ago and while the spoiler on the car was destroyed(see our other listing), the blocks were fine and re-used...but the replacement original spoiler we bought from a race team that had removed it from a 2000 R they race came with a set as well...so we ended up with this extra pair. This is it, once they are gone, they are gone.... with only 300 cars produced you likely won't find another set.
