I recently bought a set of Pitlock skewers, a front and rear set. Today I went to put on the rear skewer and the thread doesn't go down the skewer enough to tighten against the dropout. I'm trying to put it on a 1982 Schwinn Super Sport, that has horizontal dropouts. Does anybody have any easy fixes for this, short of sending the set back to Canada? Seems a shame to pay $50 for a skewer set and have to swap out the stainless steel skewers for regulars.

Thanks in advance,
