I had a batch of tie down hooks made by my local blacksmith for my 10cwt GS trailer rebuild so if all other options don't come up with sufficient hooks, all is not lost. They can still be made by hand (probably the original method anyway) if you find the right smith.

John Corden put me onto ready cut steel discs from eBay which were used to make new support legs, so again there is always a way.
