Before going about adding any washers and such I would at least chase the threads with a tap first to make sure the threads are clean all the way. Normal function is to be able thread the shifter bolt all the way without bottoming out with the shifter installed correctly. I highly doubt the braze-ons are defectively manufactured with shorter than spec threads, though it's possible as the shop that built them may or may not even check the threads. With your Riv purchased frame, don't hesitate to contact them about things that aren't fitting correctly, that''s part of a selling frames to the public, to fit the parts as intended. They want to know these things as well. If you spend 2 grand on new frame the last thing you ought to be doing is home remedies with it. Whaddaya paying for ?
