i can't say how many there are unfortunately. I got it at everythingnissan.com. The part number is 34920-P4928. It's $64.98 plus shipping but for a new knob I took it. Helps if you have part numbers. Parts guys at Nissan are generally too lazy to bother helping but I found someone at the Nissan near me who is extremely helpful in giving me part numbers. I stumbled on this site by chance: http://www.japancars.ru/cat/nissan/index.php?x=GB2&cat=260&pn=3,4,11,12,27,28,29,30&gi=F&sec=349. It's some russian site but has part numbers for all the automatic shift parts. I wish I could find a place that listed all interior parts for the 210.
