Took a look through a bunch of pictures and here is what I found.
- The AUTOLITE driver side air cleaner base decal when still visible had the black start design and did not include any info about filter replacement and specific number
- Only found these or evidence of them being applied on small blocks and 289 non-hipo applications. None on any of the 390 bases - with snorkel and screens styles
- Don't know where they would have been applied on the screen version if they were. screens don't leave allot of space in the visible surfaces of the base on the 390's
Just what I could find
