Hi Paul, I have just finished fitting the second boot floor to my 200 disco. The first was welded in some six years ago by a local garage, unfortunately it was welded to the existing sides which rotted off the wheel arches. I have made up new sides welded to the wheel arches but fitted the floor with captivated nuts and bolts. A friend took advice from his local MOT tester and did rivet his in. We have fitted a wooden floor in a 300 van which also passes the MOT. Parts for repair can be sourced from YRM.
