Yes. You can search ebay for the larger bushings. I think the .394 is 14 degree and the .405 is 10 degree. Although some distributors require filing the slot a little larger to accommodate the larger bushing. I did mine with the .394 anyway, just to assure there was no binding whatsoever. The .405 bushing comes with flats ground on the OD, but that's still not enough in some cases and you have to file the slot some.
