Dave, you are an absolute star with a welder in your hands. I bought this rear bar off eBay ages ago, and didn't have the skills to fit it. Took it to Daves place yesterday, and a few hours later was driving home with the bar fitted.
I didn't take a shot of the rear with the AgQuip step bar fitted.

Naked with no bar attached
All finished, bar the shouting
At home with the spare mounted

Side on view showing clearance.
Thanks mate.
