I have all necessary materials and tools on hand (at work
Used some 6 X 25mm flat bar for the horizontal section, bent an offset into it, drilled two holes, one for attatchment to the panel, the other to clear a 10mm bolt. Welded a nut for the bolt adjustment and added another to lock it.
So far.........



Ive now started on the vertical section that mounts behind the proportional valve.
