The title about says it all - I'm looking for whether there's a clever way to use an HC49/U in place of an HC6/U crystal case. The application (Splisbury SBX-11) has plug-in sockets for HC6/U, and a metal grounding cage which goes over the xtal packs with spring 'fingers' which reach down and ground each case. "Easiest" would be if there exists some sort of xtal plug in adaptor, which the 49/U plugs into and then in turn into the 6/U socket. I don't know if such a thing exists, though? I see one reference online but with no details, about opening an HC6/U case and swapping the HC49/U contents in. Sounds challenging, but maybe it's not? Suggestions?
