I bought the Cervinis hood that looks like the KR hood, but it doesn't have the heat extractors. Cervinis says they will be selling them but I can't wait any longer to put the hood on. Can anyone with heat extractors on thier "KR" hood take a few pictures of thiers, and maybe the width and lengh of them. I am a CNC machinist and think I am just going to make up a nice set for myself. Thanks!
