Aftermarket passenger mount compatible with AWR insert?

:
06 Mazda 3 Hatchback GT
My OEM passenger mount is so bad the AWR insert wont even work for it. So my plan was to just buy a cheap aftermarket mount and use the insert. Well after checking my local Oreilly store, I know the Anchor brand will not work with the insert unless I cut up the mount, which seems pointless. Anybody have any success with other aftermarket brands or will I have to spend the big bucks on the OEM?
