Technical Help Identifying GM Oil Pan

I have had this new oil pan (in the box) on the shelf for a long time and
I do not know the application. The printed number on the end of the
box is faded and I can find no stamping on the pan. Any help would
be appreciated.

older small block bigger truck pan. Oil return line for the air brake compressor.

 

Thanks, I couldn't quite figure of the pipe plug. I suppose that the pan would fit
quite a few applications.

 

Damn Squirrell, your middle name 'QuickDraw' ...?

 

Besides the funky stuff on the side, it's basically an early Corvette pan.
