Thanks you all in advance! This site has been a wealth of info for me . Until now I've been able to find previous threads for answers , now i'm stuck. I'm replacing oil pan on wifes 05 TrailBlazer. The old pan has 2 oil baffles/ windage trays. they seem to be perminately mounted into the pan. The new pan has no trays. It is a genuine GM pan. Did they do away with this in later years and it is not needed?? Or how do I swap the trays into the new pan? What would secure them in place. Thank you all again, I'm sure I am not the first to run into this. Thanks , Jim.
