Easy Install but install by professional is recommended！

Is there not a Hackspace in Cornwall?

Not near me.  I am also still shielding.  Anyway Wun Hung Lo's Universal Components Factory in rural China makes things far cheaper that I can for myself.
It is however several days travel by pack donkey away from the nearest decent road. So delivery times are slow.

I have a delivery stuck in the Customs shed at Heathrow Airport since the 19th of August. (20-40 days delay not unusual apparently.)

However the online advice for something that just needs two flange bolts, a couple of spacers and a couple of "penny" washers  is interesting:-

Easy Install but install by professional is recommended！No Installation Instruction, Have Mounting Hardware！

I can't order the mounting hardware until after delivery, because some precise measurement is needed to determine the length of the flange bolts needed and the length of spacers.
The joys of "universal" parts.

The one in London is full of weirdos but they can make most anything to order.
