Cheer Ben, I do love it But as Stu said, ALWAYS ALWAYS declare your mods, if you cant afford/justify the premium hike, don't buy them. And declare everything! I once heard a story where a guy had parked his car outside his house as always and someone smashed into it and drove off. His insurance didn't pay out just because he put Lexus lights on it (muppet ) )
All insurance companies want is your money, and if they can find a way of avoiding paying out they will!
Good luck with the conversion if you go ahead with it though mate
