Should say right on the emissions sticker on the core support. I believe it is supposed to be 0.042".

I believe mine for AC/Delco is .060", but definitely check the emissions label.

0.130"....??..are you sure of this measurement?
Is this for a 2005 Blazer, 4.3L V6 or a Trailblazer, 4.2L inline 6?
