We decided to do something funky with the centre part of the rear x-member - an integrated Hayman Reese-type hitch receiver built into the rear x-member itself. I would not have even contemplated doing this unless I had to chop out this whole centre section and reinstate it - which I had to do so why not! I ordered some 65x65 RHS with a 6mm wall thickness - same as what the towbar manufacturers use - and went to work. First up was to drill some 16mm holes in each vertical face of the RHS for the hitch pin, and then weld the sucker in.
I cut out the front face of the rear cross-member and replace that with some new steel (sorry no pics but you can see it in the second photo below), then proceeded to cut the square hole through the rear face and then the front face - maintaining the correct centreline alignment. I then welded the RHS to these two plates on the internal cavity to allow to ensure that the outer faces were flush.
Then we cut two reinforcing plates out of 3mm steel to cover the rear face (which was a slightly dented but unaffected by corrosion, it looked OK) and also a piece that would span the flanges on the front face and lock in the RHS. This means that over a span of 125mm the RHS is welded to 2x 2mm plates and 2x 3mm plates - which should be enough to withstand towing the Queen Mary!! I didn't take any photos on the progress but here are some of the finished product.
Rear reinforcing plate which covers the original rear plate and simply reinforces it:

Front reinforcing plate which spans the rolled flanges and reinforces this front area (also note the new steel on this face to the right and a patch to the main rail over on the far left to be done later):

And what was Plugger doing while all this was going on - getting some practice with the 5" angle grinder and technical drawing (guys, please note that Plugger is modelling the latest in PPE after the wire wheel incident :D)..
