hello. i hit a pheasant. and now need to replace bumper/skirt. have sourced bumper, but can anyone out there advise how to replace? ie does the foam have to come off too? have got some fibre glass as am a sculptor, but time and size of hole is an issue.
More importantly, i have a clucking-manhole cover kinda sound when i release excellorator pedal (not when clutch engaged). someone has suggested its my engine mounts? doesn't effect performance. usually occures at low revs and low speed.
help.

dont know about the noise but the bumper is held on by four nuts and two screws 20 minute job tops ,the foam comes with the new bumper.
