Brothers just sent me the end of summer sale catalogue and they show rubber matts ( which I bought and just installed in my 63 GMC 4x4 sub because that was period issue ) but they also showed carpets for both low and hight hump carpet for the cabin. I think the PU'S with or without 4x4 are the same as suburbans for carpets and rubber matts.
Always ready to stand corrected though!
