1st Gen Tacoma Flatbed - Getting Started

I'm building a custom flatbed for my Tacoma 4WD. This is day one, were I fab up the bottom frame that mounts to the truck. Time lapse, to keep it quick.
2004 Tacoma 4WD V6
Standard Transmission (stick)
3" Lift, Bilstein 5100s, ToyTec front springs and rear add-a-leaf. OME rear shocks (will eventually change all over to OME).
