Not the most important of parts but definetly the smallest, wondering if by chance anyone has a spare "A28" from their kit? Its one of those dead eyes on the engine cover. Will gladly pay postage.

Chances are that no one will part with one of those as they are so fragile. I suggest replacing the bolt head with a bolt head borrowed from a part of the kit that will not be visible after it is finished. Good location is behind the front idler wheel. Add a loop using wire to replace the eyelet, or an eyelet from model railroad stuff. Or just leave the eyelet off.
