How do you expect to get any advice if people cannot give you the
description and suggested source of the sought for device(s).

I am quite sure that you cannot easily manufacture the required
grounding blocs yourself????

COMMENT ON.

Affraid if you are not going to set-up a production line, you even wont
find the different elements needed in small qnt.
( And if.......At what price ?....)
