I have just been gifted a wrap round bullbar for my TD5 (2 pints of guiness) Looked at where it attaches and found looking through the air vent mesh where i think it goes. However, looks like i will need to cut slots in the bumper to fit it. Is this the case? and if so, is there a template? Don't want to go hacking away blind. Is this a ploy by LR to get you to purchase a sloted bumper? Appreciate some info if anyones has fitted one!!!
