Any question answered...

right then, im gonna need a bit of advice but il spin you a bit of yarn first: i bought my njs bridgestone track frame complete about three months ago and it was obvious that the previous had slightly neglected the bike, not terribly, but in a way that meant he hadnt touched anything in a long time. I recently got a flat, when i went to change it i couldnt get the wheel out (this is the rear.) at first i thought that the axle or the track nuts had corroded to the dropouts but then i unscrewed the nuts and gave the wheel a bit of force and the wheel would move backwards in the dropouts. i finally got the wheel out with a lot of force and it turned out that a 120mm spaced wheel had been jammed in the dropouts that were 110mm. what should i do? could i re-space the hub (high flange dura-ace 7600) to 110mm? is this even possible? what cold-setting the frame be an option? would it be expensive? or should i just sell the wheels i have and buy some 110mm wheels (i'd ideally be looking for the 7600 hubs)? are 110mm hubs or wheelsets quite rare?
cheers in advance

what's interesting about this is that i bought this bike from andy 'fixed gear' ellis london and i didn't change a thing on it, cos i'm clueless, which just goes to show what a rip-off cunt the guy is.
