Nylon thrust washers on wishbone joints

[Hawkeye1922]

OK I'm just screwing the chassis back together - I've got a bunch of new nylon thrust washers from racetech (TVR part number C0192), but there are a few bushes that seem to be a slightly larger diameter, so the washers don't fit. None of the usual suppliers seem to stock anything other than C0192. Anyone know where I might get hold of the larger ones?

cheers...
