Ok I did some measuring on the pass mount. The insulator is being pulled about 1/2" back. To mount the bracket on the front of the ears I'd have to cut off 3/4" of the thick ear and about 3/8" of the lower thin one leaving 1/4" of thickness. That would straighten out the insulator. If I don't cut the ears mounting the bracket to the front face of the thick ear and using spacers on the two thin ears then the bracket would be to far forward. I shouldn't have to cut the ears to make this work.
Actually there is another set of slots in the cross member but they are much lower and way to far forward.
The brackets look good and undamaged. Compared them with two other sets that I have.
