Took me an a mate who was the brains behind it all as he is a aircraft engineer about 5 weeks, then there was teething problems and the the clutch went so fitted a solid fly wheel conversion in there, I sold the car as it was sat in my barn for 4 months as I had a e39 as a daily and my Laguna 2 show car (now sold) I now wish I still had the car but my e60 is now a bit of a project and may sell the 39 this year to make way for a e46 convertible

Good luck with the conversion
