ball in mbc+a

I hate working on my car! Well i was taking apart my mbc so i could pull the spring out a bit because it was fully open and i wasnt hitting my fuel cut. and i fing dropped the ball down something and i cant seem to find it. is there anywhere i can get just the ball or something so i dont have to buy an entirely new mbc+a? spatl, could i buy the ball from you if i cant get them in stores? lol, this blows
