Well i got my 5 piece cab repair kit in today..Well my 4 piece i think thay ran out of stock on the rocker backing plate...But anyways my floor is pretty rotted away and im looking for some ideas..I was thinking about only cutting out what i need and taking a flange tool and making a flange on the old floor bord so i can just cut down the new one..And be able to just let it sit in the Flush flange...And then spot weld it and go over it with seem sealer.....So thay way it will Tie in the old stuff with the new stuff vary well...Any ideas?
