Graham, I did not actually get your PM for whatever reason. The details if you have a Facebook account can be seen if you search for Jaf fabrication. I paid under £200 for my tanks delivered (that includes everything). They are really good. They are also doing our tanks straps in stainless (4 straps per side, front and rear straps have restrainers also). These are our design also. We are also having them make our seats in Aluminium to our size spec. Again, price is great and you can see various seat designs on their site. FYI, paying under £40 for the 8 straps - not sure of carriage details yet.)
Nick.
