Recomendations for brackets/clamps for older pleated metal roof profile

[positivepower]

Does anybody have any recommendations for a roof clamp or bracket for a corrugated metal roof with pleats between the ribs? Picture attached. I normally use S-5 clamps for standing seam, and Versabrackets, Corruslides and Ejots for screw down roofing. This however has no flat areas, and the ribs are only 3/4" tall. Perhaps Ejot bolts through the existing screw holes? Otherwise I could try and tighten down a Versabracket and see if the metal is flexible enough to flatten out. Anyone come into this one before?
