Replying to Custome Shop GT

I want to do some custome shop on my GT..

Has anyone here had any experiance with this?>
as in waht works well and what doesnt work>?

right now my mods consist of replacing the streening wheel with an old handle bar and stem (biking)

I want to throw on my old skis but im not sure how.

I was also considering trying to put a big dirty suspension fork off my old bike, but im not sure how, and even i got it to work the thing would be at such a crazy angle.

I want to make this thing kick ass, so if you have any ideas lemme know!
