In answer to some of the questions :
The Simmonds steering wheel is cosmetically nicer than the original it is very slightly smaller and does give a much improved view of the rev counter & fuel gauge.
Front inner tubes: have an offset nickel plated valve , superior Blockley inner tube, so they are heavier than a motorcycle tube. If you are touring I would suggest for the sake of a few pounds you carry a spare, you are not going to find a substitute easily.
Tool Box: I am located in Northampton the traditional home of the boot & shoe industry so it was nice to find a local person to make the box. It was dyed to match the interior colour and is lined in black goats skin. Obviously you could choose a colour to suit your car. I should make it clear that the box is bolted to the car.
