They recommend pushing the plug out via the bleed port, works, but def damages the diaphragm and thus removes any chance to inspect for the initial problem.
Also has part numbers, got mine from amazon, but number of UK/EU shops also have stock.
And yes def attached funnel when pushing pads back, especially is you have done some over bleeding mid pad wear.
