F250/350 Shocker install help needed

Hey there, new to the forum… installing some horns on my dad’s truck and need advice… he doesn’t want to spare tire delete but wants the shocker XL horns installed… I cannot figure out a place they will fit… any installs you got out there? Hit me with it!
Thanks!
