I did see all those control arms .... I see the entire corner falling off once it is torque (rotation) loaded to that extent. But only you would be in a position to judge the weight of the top piece and extent of base cracking. If you do want that angle then, as ugly as it sounds, I would wack that corner flat on a bench and see if it cracked and fell off - better off to know now than later. The red is the piece I see falling off when I look at existing cracks and grain.
