WANTED: Bathroom Washbasin brackets (Kington HR5)

Wanted
Bathroom Washbasin brackets
Kington HR5
DESCRIPTION
Can be any colour as they will be hidden and I think they are usually metal. I have some but they are too short. From the back of the bracket to the lug that fits in to the base of the basin needs to be close to 36 cm but I could also use other strong metal brackets without a lug and use strong glue instead. Thank you very much
