Thanks to everyone who has replied!
Here is what I am dealing with;
http://www.flickr.com/photos/our__lives/2309565943/in/set-72157604045422587/I think I will probably go the Under door rocker and add sheet metal to that. I am aware of the "inner fender" in the rear, but that looks easy compared to the rockers. I have yet figure a way to rust proof the inside when I'm finished. I have an old cab section that I bought for the good floor. I think I'll cut one of the door rockers and experiment with that, though I don't think that they are good enough to use on my truck.
Thanks again,
Les
