2016 Silverado 6.0 Driver's side manifold replacement. THE PART IS AVAILABLE.

Here we see the aftermarket making a mistake and listing the wrong part for the driver's side manifold on this engine. I've checked all the major box stores and some private ones. A 2007 Silverado 5.3 manifold is a direct replacement. Excuse some of my terminology as I didn't rehearse this. I should also add they specifically ask which transmission this truck has for the part lookup. Mine has the 6l90? I believe it is, but I can't see it making a difference.
