Yes I am using original 71 headlight brackets. But I am mounting them on a 73 model cuda. The picture helped. The hole should have been where the two panel overlapped. The problem was there was no hole on the radiator support side. I drilled the hole through the other half of the panel and it lined right up with the hole in the bracket. Now if will works the same on the drivers side, I will have it made.
Thanks for the help and the pictures.
