@ Fastandfuture:
dude wht i did was; i went to scrapyard and bought a number of compnents from a quad bike... the front steering parts, the rare axle parts, breaking system, engine, tyres, silencer, break cylinder and etc etc...
the front steering compnents had to be redesigned and modified according to our requirements but it will give you and your mechanic a very good idea how to go abt it...!!
