Now here's where mine is different than the rest I've seen. I wanted this to be a little different than most, so I chose to leave the extended cab wheelbase alone. What this would give me is a box that is longer than a shortbed, but slightly shorter than a 3/4 ton bed, and way shorter than my original 9 foot bed. I purchased some junk short bedsides off craigslist for mockup, and some OK 3/4 ton bedsides to use once I figured out how long I wanted it. Since I'm very particular about how the wheels sit in the wheelwells and since I had complete control of where this was...might as well get it exactly where I wanted it.
Here's figuring that out:
I wanted the longer bed because I plan to use the truck for my all purpose hauling, summertime truck duties, etc. I also wanted a steel bed floor. I had planned to use an 88-98 floor, when I saw a guy use an s10 floor on another forum. This was perfect, it allowed me to re-use more of the s10 and the bed mounts were already there for this!
