GU patrol and side steps

Just had some TJM side steps fitted. While checking under the car noticed that the passenger side rear u-bolt that clamps the step to the chassis had almost punched a hole in the floor pan. The bolt is to long, needs about 10mm cut off. Checked the other side and it was similar. That's not the worst of it. To get the bolt past the aux fuel tank they had to flog the tank seam up to make clearance for the bolt to get past the tank, chassis and fuel lines. So not the bolt hits hard against the fuel lines and tank seam. This is on a cab chassis but I'm pretty sure the wagons aux tank is in the same place. The side steps were supplied and fitted by TJM but my understanding is that ARB etc use the same design. This is a design fault so I don't necessarily blame the fitters but head office. Of which I've had no reply from an email I sent via there web feedback service. Thought you might like to know so you can all check if you've had similar fitted.
