Well I got it fitted today, luckily it was all very easy and went without any issues at all. Luckily my Discovery is in very good order underneath and was just a case of cleaning the holes the bolts went through to ensure they went in okay. To be fair, it was easier than I though, which makes a change for me when it comes to anything Land Rover related!!! Time to do some towing now. Thanks for your help once again!
