The clamp contour is based off the MIC/other design. Their rack exerts immense upward force when the clamps are joined, thus the cracking/splitting of pieces.I'm currently in the same boat with the painted roof and shallow pocket. Who would have thought pocket depth envy was a real thing... I jest. Quick question, was it just the foot that inserts into the pocket too long? Could the foot be trimmed down to the 1/2" and fit? Or is the width from left pocket to right pocket also further apart? I'm assuming it's only the pocket depth that's different and a shorter leg that goes into the pocket would work. Can you tell where the crack happened?
A design where clamps are assembled first and a rack bolted onto that would be the safest bet. Prinsu racks is an example.
