Trouble finding an air filter

[Bleach]

This is the book that I have. I got it thinking it would help me find the filter I needed. Wrong plus now that I know from you that there are other books covering the other makes.
It's not a total waste. It has listings for all the other parts and specs the FSM does not show for my 56 Ford.
I can take photos fairly easily now. I found an old smart phone that I have that is compatible with my old macbook. It's a Motorola. It doesn't take the greatest photos plus my hands shake makes it harder. My iPhone which is fairly new will not work with my mac. What a bunch of BS. It takes great photos but are a big PITA to download.
