Okay, go to town2 lower area and look under the area you can't see there you come up to one navi to buy for 2000 z's
Then when you get there town3 (the path from park area and talk to a navi that come out in the open once in a while and buy that part for 3000 z's
Then the last part is in yumland area and buy that one for I think is 4000 z's
then go to sharo from a path in netfrica and talk to the guy in the back with a c slider path he says you have to find the c slider master in sharo area. Go to sharo area and find a gate, pay 500 z's and talk to the girl navi there and ta-da you very own c slider. But be warned once you get the game and start a continue 2 (and so on) you will have to get the part again.
