(For jacking). I grovel under the car, as best I can, and I wonder about the seam running down the centre of the chassis members…..they bulge(?) downward/outwards. And that, presumably, will hinder getting the plate on nice and flat.Now, is that seam a hollow bulge which, if ground off flush, would cause the cross-member to split? Or, is the seam a weld? ie the chassis is two U-sections welded together, top and bottom….So, a bit of judicious grinding wouldn’t hurt.If you see what I mean…?Simon
My Interpretation on examination on my frame is that the seam is 'edge welded' .. the two pieces of the frame were shaped/bent in a C section with approximately 3/8" flanges on each edge.  These were then joined by welding along the edge of these flanges.
Why not make a flat plate with a groove down it to fit on your jack to mate with the frame ...the flange fitting in the groove flatly 
stabilizing the jacking point in the process
