Are you talking about the sleeves that hold the CAI to the MAF, etc.? I have one extra from my old Mac CAI (trashed it after it caused some problems for me) - you could have it (I'm down in Redmond). Also, I called Mac and ordered a 3.5" for like $12.00 - still seems unreasonably priced, but it's better than $30.00. You're welcome to what I've got.
