I had a look at a company in the UK before I went to the USA. This company already manufactured zinc U bolts and saddles and for s/s ones they wanted a MOQ of 5,000 and the cost of the U bolts in s/s would be aprox £10 to £15.
The cost to me from the USA in s/s was $9 each this inclued P&P and taxes, I also thought if the demand in the UK was worthwhile I would import them and sell them on but there was not enough interest.
Perhaps Morgan Motor Co could buy them and fit them onto new cars and also retro fit
