If you are going that wide you are obviously going wheels under so just cut off the side rails flush. build up just enough to clear the stock fenders and then install your floor. When I did chubby I cut out the floor around the fenders and let them protrude thru but didn't like the little 1 1/2" boxes so I put down 2 layers of 3/4 foam cut out arouns them then sealed with spray foam just before installing a 7/16 floor over the fenders inside.
I now have an insulated floor and no lumps. Several pics in my album.
Growing older but not up !
