Center arm rest
 

Hi all, I am going to replace my center arm rest because it always make grinding sound (just like something cracked). Can anyone here tell what the difference between item 5 and item 10? It looks like same but item 5 has the leather cover and item 10 doesn't, however, item 10 is more expensive than item 5, this really confuses me. Thanks for help!

#5 probably wraps OVER #10 so you'd need to buy 5,6 &10
