Got the rest of the parts back from the welder today. Wanted it done correct, by a skilled person that has a powerfull enough welder.
Time to mock it up in the rear.
Bracket test fitted, (only one bolts on each end) the other two where to short.
From the back
Time to make a cut in the bumper, for the hitch neck.
Measure twise, cut ones.
Bumper test fitted with hex bolts, the two outer ones needs to be drilled.
Got it exactly like I wanted it, Brackets resembles the original ones but a lot tougher, the beam is hidden inside the bumper making it look like the hitch is attached to the bumper at first glans, but it turnes out that its actually the other way around, the bumper is attached to the trailer hitch.
I have made improvements on the design so the whole assembly is good for 2500 kg (5500 lbs) according to regulation standards (on paper) however the regulation doesn´t allow me to pull heavier than 1500 kg (3300 lbs) without a physical fatigue and an official ford document stating the allowed towing weight for a F100 -56. So I belive I'am satisfied with 1500 kg (3300 lbs)
