the steering shaft is two pieces. drill out the four pins, two on each side and good luck seperating the two. some advice, get some penetrating oil(everyone on here loves PB blaster) and pour it down the end of the shaft and let it soak for a few days if you can(over night at least). this will greatly help in getting them apart. i havent ever swapped a boot out so cant help you there.
