Budnikguy-
You should have received the inner frame stiffener without the slot cut holes. Then it's a mock it up, mark it, and drill new holes.
We made a small change when we updated the design, and this is causing the fitment problems.
Do me a favor and shoot us a call or an email and we will go over a couple things and get a new set of inner frame supports out to you!
Apologies for the inconvenience.
Nate
