Heres the final drawing of the engineers plans who fitted my sons tank in the van. I still have not got around getting photos of it yet as my son is spending a lot of time at his girlfreinds.
Its pretty darn good though.
By all means feel free to use the drawings if you are getting the same style of tank. A local engineer or fabricator should be able to build and fit the frame for you.
If you dont mind travelling the company will make and fit it for you, the tel no is on the photo. They would like the tank and fittings if you want them to do it, as they build the frame around the tank. They are specialists in stainless steel.
