Whelen Howler bracket HWLRB27 for 2019/20 Expedition

[jayzce]

Does the HWLRB27 fit either the left or right side?

Planning on getting the 2 Howler speakers, my question is will this bracket work on both the left and right side of the Expedition?

Checking the install guide it doesn't say, it is designed for the sa315/howler setup and only shows one side of the vehicle based on how it installs, and there's no other data. Hope that is some help.
My best guess based on the install guide is left side only, will email my tech to see.
