The fork tubes are 41mm but the shrouds surrounding them are 57mm. Take the shrouds off and they'll work.
One option if you're leaving the shrouds on would be
the rivco mounts from newspeedmaster.com however I'm not sure how the pumpkins bolt to them and if you could replace the fittings with the 5/16" ones required for the silver bullets... you might want to email Brent and ask him.
Another option is the
turn signal relocation bracket from Ma's cycles. They say something about needing the "correct spacers" with silver bullets, but they don't say what sort of spacers those might be. Again, write an email and ask I guess.
