Thanks for the feedback guys,
Yes i will do something internally shortly to reduce the rusting out.
Hendrik, i just have to finish off my new rear bar after I ended up selling all the other ones i'd made then it's onto a set of sliders/doorsteps.... hopefully this will give some more ideas and motivation.
Here are some photo's in the daylight, i just need to find some of that thin rubber trim to put arounf the panel cut to finish it off.
