Hey, folks. I've got an old mountain bike that's been turned into a city bike, and I'm pretty pleased so far. I put SKS Longboards on at the beginning of the winter, and they surprisingly fit fairly well – except for the front fork mounting.

I think that the MTB fork is proportioned so it can be replaced with a suspension fork, and is longer than strictly necessary: my front fender does the whole 'point-at-the-sky' thing at the front. I tried the Fender Flute thing but it was far too wide for the inside of the fork.

Can anyone suggest a piece of hardware that I can use to get that sucker further down? I'm picturing probably a long slotted bracket that's narrow enough to fit into the fork crown (either before or after filing/grinding down), but I'm not sure where to look.
