the eason for the z is just a different way of doing a stock floor, by putting 2x4 at the top oof the frame it allows you to then cut the bottom of the frame off, then z the front of the truck the amount that you cut off the bottom of the frame which is great if your building a truck on a time frame or working with a bigger vehicle that would be a big pain in the ass to take the body off if you are limited on space which it looks like tre5 is.
