    What gauge sheet metal should I use to replace the floor areas above the body mounts? The mounts are not in bad shape, I'm thinking of buying the slip overs and then welding in the floor pieces. I also need to replace the rear tailgate area, is there a corrigated sheet metal I can get to replace the back section without buying the 2-$75 panels from LMC or other places? /forums/images/graemlins/tongue.gif I basically am wanting to buy a couple sheets of metal to cut and fit to what I need /forums/images/graemlins/deal.gif /forums/images/graemlins/thumb.gif
    While I'm doing the mounts I would like to do the poly bushings and some lift pucks as cash allows!

    What did you use, good/bad, ideas?
    I have rust int he floor panels so I may try the plexiglass peep-holes in the floor boards that where descussed a while back /forums/images/graemlins/grin.gif

    I just did this to my son's new K5 project. 16 guage for the floors, and cut an extra piece (like factory) to go over the mounts. On the back, we cut out the flat metal cross piece which has the rear body mount built in. If you cut about 1/2" behind the forward edge of the rear "C" chanel (the flat metal piece) then it will come out and leave the floor (you'll miss the spot welds). On my son's, the only damage to the corrugated floor was at the very end and this got rid of it. I replaced it with a 2"x3"x3/16 square tube all the way across, extending under both bed sides (so I can tie in the bumper ends). To replace the mounts, I welded the 2 flat pieces of steel from the old piece to the bottom of the new piece. Then, for a spacer (replacing the stock sheet metal spacer) I used 2" lengths of 1"x0.120 tube with 3/8" spacers to locate them correctly.

    I dont know if you're doing the fronts too or not, but emmetology101 (mike) is selling 2 new front pans for $20 each...

    I've never had to deal with rust till now and i'm just as much of a novice as you...
