When my exhaust was fitted the guy had a basic fibreglass shell with a basic frame screwed to the backrest that accepted a headrest, it was totally unupholstered. I asked about it and mentioned ADR talk and he said it was "older" ADR approved.
A seat shell is a pretty basic thing if its made from fibreglass/ carbon fibre or even a pressed metal shell or tube frame.
The critical measurements are given, so theoretically it would be easy to make something to spec and then get it upholstered.
Apart from the probably frustrating wait and dealing with gov depts what would be the cost to get say... a well made glass shell compliant if fixed back, no tilt, not designed to be used where luggage protection is required etc?
