ONLY the steering wheel man!
no need the knee part.....!
remove the horn first,
make sure your wheels are pointing straight.
theres a big nut (about 19mm-21mm) in the center, remove via tyre cross wrench.
it should come off, but hit it if you need too.
install the new steering wheel onto the bosskit.
tighten all bolts in a cross pattern fashion. (just like tires)
install wheel+bosskit onto the spline (the rod with teeth)
and make sure the wheels about straight, install the nut about 2 turns, and go and drive to make sure the wheel's straight. If not straight, remove nut and 'tune' till straight.
once straight, tighten nut.
install horn button :)
