Personally, I would just contact Eric (Skuterdude) and get his if you haven't lost the bracket. His is poly and designed to fit the OEM brackets....If you lost one, yeah probably much easier then messing with Ford's supply chain BS
The OEM bracket is super beefy and I would suggest you keep it if possible. Bolt specs are posted earlier in the thread for those that are missing
I've got 1k miles on my Skuterdude bushings, OEM brackets and replacement bolts. They work well for me - no squeaking that I can detect.
