I have a 97 F350 chassis in my yard I am thinking about building and I want to convert it to a dually. I know where a good bed is real cheap. The bed floor is in great shape. But the area around the wheel wells is rusted. Not a big deal considering I am cutting that away any way. I also have a friend with brand new Ford flares for that model year. So I can have this bed done for a very reasonable amount. Is cutting the wheel wells all there is to this? Are there any structural issues I should be aware of? I have looked at my 95 ford dually and it looks pretty cut and dry. I want to make sure I am not missing anything though. Have any of you done this before?
