Picked up a trek 930 mtb but the guy swapped out the front fork with a suntour, it's weird because it has about 2" of threads above the headset and then he stuffed the quill inside that to mount his handle bars.

Would I would like to do is wack those extra threads off and mount a quill stem adaptor and but a new sten and handlebars on it.

This can't be right, I don't see any spacers in the headset either it's like he just screwed it down till it got tight.

Unless someone's got a trek fork for an old mountain bike sitting around to go back original?
