I kept a couple of sets of the old microfiche, one from 84 and the other from 88. They were good because back then they would usually put what the part fit at the back of the description. By the early 90s we went to the computer discs, which did not usually say what the part fit, but gave equipment application codes (for a M113A1 it was 30670 if I recall) for what vehicles the part was applicable to. Priblem is that by then the Jeeps were long gone, and those parts, if they were still listed, would not have the EAC.
Neat thing about the old microfiche is that there are still some parts and tools listed for CMPs and UCs.
As I recall, we replaced all the aircleaner housings back in the 80s, and there was a new size of airfilter. Yours is likely the old size.
As an alternative to finding a set of the NSN listings, there are sights on the internet which will get most of what you are after. Hit or miss whether they will give you the application mind you. I like the ISO listing:
