as I always asking but now I have some information.
recently I want to replace my old ball join and you can see that a groove at the lip of ball join is a mark to install at the same place at the wing holes, my english is not really good.
the different brand has different mark so it is the opposite from the original mark (groove)
I will send you the pics so you will know what I mean.
if i wrong to install it my ball join will be broken.
thank you
