just pay up and get the shop to redish it. even if you swap spacers around the axle it needs to be redished anyway. unless you're handy with a spoke key which, no offense, i assume you're not since you're asking this question.
But like Ed says 15 dolla for a redish is prob best bet.
But all in all, its cheaper and easier to just have your wheel re-dished.
re-dish, doubt you can get the cranks any closer in. Miche do a bottom bracket that is cheap and adjustable but it looks like the teeth might hits your stay. Jut re-dish and get riding!
