Ruut, if you are handy with a TIG/MIG/Stick welder I can send you some pics of the ones I made for our Plus Six, the only cost was for the stainless rod and the upper and lower connectors, all available on the net. I made some custom parts with the TIG for the rod to stow away like a conventional bonnet prop.. If you want to purchase ready made then as Richard says Williams Automobiles which is just North and East of Bristol ( so less than 3/4 of an hours drive from Malvern ) should get you kitted out.
