1975 Slant 6 OEM pictures?

Hey everyone im cleaning up my engine bay and trying to have everything match the OEM look of the motor. Ive been on valiant.org, and slantsix.org looking for a factory picture of one of these motors from 1975 so I can have mine as correct as possible when I put it back together this week. Ive seen a lot of personal renditions of what its supposed to look like but im trying to be as correct as possible. The picture below is something I found searching online but id like something a little more high quality.

Can anyone help me out?
