well this all started with wanting the look of an or-fab bumper but the strength of a jcr bumper which i didnt see in or-fabs
so i started looking around for ideas and other bumper options and just wasnt finding what i wanted
so i sat down and started up autocad and got to work
with the plans layed out i only found one problem
i didnt have a bender
so after some more searching i found jeeptubes and contacted Mark
they had a wrap around bumper and after having him change the lower tube and adding a couple peices i had the parts for my base on the way
so now i needed to tie into the unibody
nutstrip HA
i started by opening up the rear of the unibody tubes
(id suggest using a cut off if you follow this and not jumping to the torch like i did as your fuel lines run into the unibody tubes and one rusty pin hole and you could find your self having a bad day ..my gas tank had been removed at this point)

well look at that hole plenty of room for some 4x2x3/16 tube
so after drilling some holes, welding in some nuts and cutting around the fill hoses and rear leaf spring bolts i had my nut strips

now how do you create a round tube bumper with the strenght of plate and box tubing so you have recovery points and towing capacity
thats it you create a backbone for the tube to attach too

some 5x2-1/2x3/16 sleeves over the 4x2 nicely and is perfect to cope out for the 1-3/4 tube keeping the tube at a 2-1/2" spacing
joining the 5x2-1/2 with some 3x2x3/16 tube allows you to weld along the 1-3/4 and gives a place for the receiver tube
inside the 5x2-1/2 is 3/4x2 plates welded to the inside for d-ring tabs and then cap the tube with some 3/16 plate
once the back bone is done add your tube
