What this bracket actually does
This isn't the deer guard itself - it's the steel bracket that bolts the guard assembly to the Cascadia's frame rails up front. Freightliner ran a few variations on this mount through the 2018-2024 model years depending on whether the truck had a set-back or set-forward axle, and whether it came with the factory guard package or had one added aftermarket later.
The bracket takes a beating even when nothing hits it - road salt, vibration, and just being bolted to a frame rail that flexes on rough roads will eventually crack the mounting ears or elongate the bolt holes. When that happens the guard starts rattling or leaning, and that's your sign the bracket needs replacing, not just re-tightening.
Why all these numbers cross
64-99005-B, 8-F10-B, 8-F14-B, 8-F20-B, and 564-99801-B all show up because different manufacturers cast or stamp the same basic bracket shape for the Cascadia mount, just with their own part numbering. FIT-016AS33-B is a separate aftermarket line that fits the same bolt pattern. They cross because the frame rail spacing and bolt hole locations on a Cascadia don't change year to year within this range - the bracket is doing the same job regardless of who made it.
Where you can get burned is bolt hole diameter and bracket arm length. Some of these brackets were made for a shorter guard arm setup, others for the longer reach guards. If your truck has the extended nose guard, double check arm length before you order, because a bracket that's technically 'compatible' by frame mount can still be wrong length for your specific guard.
Surest way to confirm: pull the old bracket, read whatever number is stamped or cast into it, and match that against what we've got listed. If the number's rusted off or unreadable, measure bolt hole spacing and give us a call - we can usually nail it down from that plus your VIN.

Frequently asked questions
Does 8-F10-B fit my 2020 Cascadia?
Probably, but confirm with your VIN or the number stamped on your old bracket first. Freightliner changed axle configurations across these years and the bracket needs to match your frame setup, not just the model year.
Is this the same as the 564-99801-B bracket?
They cross-reference and are built to the same mounting pattern, but they're not identical part numbers from the same manufacturer. Functionally they do the same job - bolt the guard to the frame rail - so either should work once you've confirmed bolt spacing matches your truck.
My guard is loose but the bracket doesn't look cracked - do I still need this?
Check the bolt holes first, they elongate over time even when the bracket looks fine. If the holes are worn oval instead of round, that's your problem and a new bracket will fix the rattle. If the holes are tight and it's still loose, might just be bolt torque.
