The trick is that you can't. The Anthem is a semi truck, not AR Frame. Look at the names of the mods, if they have "AR" in them, they you can attach the beds, if they don't = they can't.
I miss read the pack name, I was referring to the anthem in the mack ar frame pack. My mistake
There isn't an Anthem in the AR Frame pack. Only the old Mack
It's another mod pack all together, I selected the wrong one in-game. I did however download the Peterbilt 359,, all is well.
