Thanks all Iae or Bateman etc. may sell them separately but they're not listed. Don't think anyone including @Fraserb would compete with the first link at £0.50 each but not wide enough. Will also try agriparts tomorrow know he has weld on crooks etc. but not noticed the lugs before. Will also try the local blacksmith he has a metalworker not sure if it's big enough for this job though.
edit. Also some listed on ebay now never thought to look there.
