H: 6" (In the middle) 4.25 (aprox at the end of the bumper, its hard to judge with the curve)
The middle section is 39.5" then its cut so you have to cut out a wedge and bend up the excess along a curve at the end. Hard to explain but if you look I think you can understand.
Make sure when you buy the rectangular tubing that its longer than the actual 74.5 because you will need excess to bend up along that curve. This is how my front bumper was made to match it and you can see how that bend and curve is done.
I'm going to build one my self and need some dementions.. How long are the frame mounts from the back of bumper to the end where you bolt it on to the frame? Also how long are the wedges in the front of bumper where you put the shackels and how big of a hole is that driled threw their? opc1:
