Correct! When I talked to Joel at Metro years ago when was first developing this part, I asked which it was, the upper or lower. He told me they were both the same, at which I answered that no, they were not, and took his piece to my car and showed him the difference. I told him he got lucky and picked the lower to repop, which was totally a shot in the dark because he was using the best piece he had as his template, which just happened to be a lower.
