Here is a novel idea, next time you want to start a thread and don't want to make yourself look like a idiot take a walk out to your truck and take a look at it so you know what your talking about. Duh it's riveted in? Duh I don't have to section the floor just cut the lip down. LOL
Tuk tuk, the crossmember has two rivets on each side. You can lift it an inch, and trim that inch lip from bottom of cab. If you scroll back a ways, like first pages. Youll see pics from when I did it.the first time
