Hi guys well I have run into a problem I seem to have lost a part. I think it is a tubular insert with the approximately the following dimensions 50mm long 47.5 mm OD and 41.2 mm ID.
Now if I am correct i can get one made but if it is not a simple tube then i need to know. So I'm asking does anyone know if it is a tube or where I may get a replacement.
You can see it in the photo below as it protrudes through the backing plate before i disassembled that section.
