Interesting update on "crappy" repro fan shrouds

I bought one of the repros some years ago and it warped after a few heat cycles. I took it off and redrilled the holes and reinstalled it. It was good for a day or two then it warped again, so I ground some more on it. I reinstalled it and it was good for a little while longer but then warped again. Finally I had enough of it and called Year One (the supplier) to let them know that it was a POS. To their credit they took it back and issued a full refund, even after I had redrilled it and ground on the mounts. I think the material has to be changed if the new shrouds are going to be successful, the old material was just too susceptible to heat.
