I mean the threaded bit of the RJ goes into the tube, and at one end (or both) the through bolt goes through a double shear bracket with the bolt vertically.
Or the same orientation as in the track locator.
So really the track locator in the pic would be at right angles to the chassis c/l and used as a panhard rod.
If I am really lucky, all the bits will fit without modification.
(Ever the optimist)
