Hello All , Could do with some help please . Is it possible to buy a close couple kit where the metal plate is flat , not raised where the bolt slots are ? I did a job recently where I had to replace the syphon and the plate was very rusty , tried replaceing it with the modern raised style , but it didnt fit . I just put the old one back with plenty of silicone and no probs so far . It is bound to happen again though and just wondered if anyone knows of a supplier ? I guess I could make some out of steel plate , but I would rather not spend time doing it . Thanks .
