It seems like every time I get closer to finishing this swap something else comes up.

I forgot to mention it's an 03 5.3 but I don't know whether it is a HD or 4X4

if its a 5.3 then its a 4x4

Thats weird I've never seen a pan like that before. I've got a truck pan for sale if you need one.

Isn't that a Trailblazer pan?

According to this site LS engine oil pans - all of them it looks like the TBSS and 5.3.

Envoy, Trailblazer, Rainier...yes the the front axle goes through the pan on those :argg:

Thanks for the help guys, looks like I need to get a new oil pan now.
