what is very common but not mandatory is keep the PN visible on rear


Makes it easy to ID what you have in there if you lose track but can go in either way. If your bars have a L and a R or an odd and an even # to dictate which side they go that is critical and on the ones that are not marked and are therefore not side specific either side is OK unless they are used in which case they need to be marked and returned to the same side as before.
