Jethro,
you're correct, i did reuse the mounting brackets. They were re-welded in the same position on the other side of the pipes.
Give you a run down. on a steel bench top, i welded some scrap angle standing upright, and drilled some holes to allow me to bolt the pipe to it so it was like a jig. I then welded a couple of smaller bits on an angle for the mounting brackets.i cut the bars thru the solid part at each end as the pipe are hollow. Turned the bars over 180 degrees, and tacked them to the ends that were still in the "jig". Cut the mounting brackets off, and inverted them. Lost a little bit of material height in doing this to the mounting brackets, but i would of needed the spacers anyway. Once it was all tacked together, took it off the jig and fully welded it, cleaned it up then had it re-chromed.
If you look closely at where the bars normally mount, you will see some small chromed spacers to stand out the bars away from the frame, it also set the distance right to miss the exhaust.
I am just short of 6 ft but sit right up on the tank, and i find it quite comfortable on a long run. The only fiddly bit was trying to neaten up the brake line. Although it doesnt show it in the photos, it still looks messy to me. i will probably get around to re-running the whole line in new tubing. The selector rod was as i described earlier. They normally bend anyway, but there is no way this one will.
