Straightedge across pan flanges showing standoff height relative to pan flange. This was the same as the #24298919 pan that is currently on the car.

Pan total depth from flange to bottom. About 65-66mm. Pan was sitting flush on a Longacre scale pad...nice flat plane. See next photo for exact location this measurement was taken. Pan does have a slight taper front to rear. Please measure your pans from the exact spot I did to minimize this variable. and report the # along with the pan # you have! I did not do this when I did the swap a few years ago. It is possible the two pans I have are different beyond their same standoff height.

Notice blue lines that I created with the level to call out a consistent spot to compare depth.

Attachment 1172182


Standoff height, 55.8mm.

Had I known all these measurements when I did the swap I would have seen I may not have needed a different pan, based on standoff height alone. But, GM makes part # changes for a variety of reasons. As noted I did not check the #24298919 pan depth.

Thanks a bunch for this!


I'll have to check the 24043536 pan and report back. It appears that the standoff is considerably lower just eyeballing it's relative height to the mounting flange surface for your 3537 1LE pan (which is the most current PN GM offers compared to my 3536 one.
