      I returned the part as I did not need to replace at the time, but it looks like it would fit good if you can get the manifold nuts off. A small strong semi-flexible swivel on a 15mm air socket with a long extension will get you over the top of the converter to the top flange nut on the 2007 Chevy Implala.
