What the heck is going on here?!

Nothing like a Part, a Vehicle, or a System that requires YOU to work around THEIR lack of design! You'd think that for the Premium price, something that basic would be included.

Man that really sucks. Aparently their R&D department didn't do their job that well.
Unless it has to do with the strength and that's why it's designed that way.

so how would you design a TUBE upper arm to clear that little tab and us the bump stop??
