Shim the sucker in and see if tuning stabalizes. As to whether it is "important" or not depends on how well it is screwed to the plate, if it is mortised into the case or stretcher, or is more of a free floater. In general, if it is NOT important, then a kajillion manhours have been wasted by manufacturers and rebuilders to bed the suckers properly!!! Yes, it's important. How tight are those pins? It seems like "rocking" instabilitiy wouldn't take two weeks to show up. Since the customer is confused by previous advice and research, if the flange fit IS a problem but the pins are tight and I think I'd flip it over and use wood and epoxy to fill the gaps rather than try to sell a bigger job. Don't forget the drop cloth!
