Thanks @rainbowreality. I do use duck duck go most of the time, but for some reason there are times when google has more options .
I found the folk at Glued to music really professional and friendly. They were doubtful that the screws they had were suitable. I would contact them again if needed !
I have a friend up north who is always super busy ,and who runs his own guitar shop. I managed to make contact with him yesterday , and the replacement screws are on their way !
