TonyS is another. I've got my kit but haven't had the time to fit it yet, looks straight forward enough though.
If you want to save some money buy the car kit(s) with someone else and split it - you get two of everything so it's not a problem - and if you explain this to them when buying they'll drop in two copies of the motorcycle fitting instructions in place of the car.
They will also do a deal on a bulk / group buy. 10% on 5 car kits or 10 motorcycle kits.
Janet in sales was very helpful.
