RB,
I did considerable research recently, to install all of my decals, on Pagoda World, You Tube Video by Will Samples, Mercedes Benz Star magazine, and this site. I posted some questions on this site to clarify the "130" valve cover decal placement. The only decal that I found for the AC was a silver one that wrapped around the dryer but did not come across the ones you have posted. Not saying they didn't exist but I did not come across them in my research and until now did not even know they were sold. I would call George at Authentic Classics and ask him. He may be willing to share how he determined they existed and where they should go.
Please share what you find out and Good Luck!
Tony
