Anyone know if the left and right side CV Boots are the same BMW Part #?

I recently bought the left side boots which were:

31-60-7-507-402 - outer
31-60-7-507-403 - Inner

Now I need the right side boots, RealOEM.com does not specify. There is a A version and a B version which is confusing me....
