cut out some of support bar.but its still the standard bumper
had to remove grill section at bottom only and some of the bits that hold fog lights in nothing major.
the guy who fitted the tanks and pipework works from home and he's never done car stuff before (alloy boat builder).mine mounts the front of the chassis rails and ties into bonnet catch at top.
i will get you a pic soon, pity i didnt take one with bumper and support off it looks awesome then. its tapered at top to fit under headlights its so wide
