67-69 Dart rear bumper brackets any differences?!?

I've got a member who wants to swap me rear bumpers. We both have 67's. His has a 68-69 bumper on it, and he wants to swap for my 67. My car has 68 tail lights and I will be using the back up lights in them.

What we need to know is there any differences in the bumper brackets. Both bumpers look the same from the outside, but we don't know if some previous owner changed the brackets on his when they put the other bumper on or whether they just swap straight out?!?

Mine



His



He is going to bring his bumper to me tomorrow, so we kinda need to know if he needs to pull his brackets also. What do you all think??? Thanks!
