Thanks guys! The information and photo's were just what I needed! Looks like a real easy install after seeing these. I think I will go with the under frame with channels so it will be easier if removal is needed. The fun began today as my helper and I stripped all the sheetmetal, doors, and box off the truck. Then completely power washed everything. The cab was alot heavier than I expected so we will be removing that tomorrow with a proper lift. Man, the floor vents and cowl drains were solid full of mice nests and lots of good things! It took awile to clear all of that out completely. The good thing is they are not all rusted out. Well, It's a start.
Thanks Again
I will take photos of the process and post them soon.
