what it takes to lay body

[rgreathouse]

hey guys i was wondering what it takes to get the pinch molding to lay out. i kno theres the porterbuilt drop member but im not going to fork out that money.is it possible to do without cutting up the floor?is a combination of a z and crossmember notch necissary?ive done a z before so this doesnt concern me but im not sure if this is enough.any help would be appreciated. oh and id like to set it up on 20s.
