evo 1,2 and GSR are the same....evo 3 is the odd one out.
just get them to count the teeth and then you are sure what you will get before it leaves. I have bought some gear from them before and it was an easy deal, he sent me some guards that were mint.
keep it in mind in case you cant find one.....
I would like to see what Im getting before shelling out for a used item too
