I think you are looking for a function like this:

function FindMyComponentIndex(
  Selected: TMyComponent; 
  const Components: array of TMyComponent
): Integer;
begin
  for Result := low(Components) to high(Components) do 
    if Components[Result]=Selected then
      exit;
  Result := -1;
end;

I trust it will be obvious how to call this function.
