Whelen Inner Edge XLP Bracket for 2015 F-150

[DaveCN5]

I am in search of mounting brackets for a Whelen Inner Edge XLP Ten head with 2 TD's for a 2015 F-150. I see it is listed on their website and have scoured the internet and multiple sites and can't find anyone that has them. Any help appreciated.

The part number for the whole unit is IX47UFZ.
