273 Commando Air Cleaners and Valve Covers

Jim Lusk said
The same air cleaner was used on some big blocks, but was painted black. There is no repop of the correct silk screened aluminum applique. There were also some with the nipple for the valve cover breather and some without. Every one I have owned had the nipple, but that's probably because I am in California.

The valve covers are close, but they also had a special wire holder by the carb on the passenger side cover. 65 and 66 used the same covers. 67 was the first year of the grommet for the PCV valve.

The 273 aircleaner is actually smaller in diameter than the big block aircleaners if you are talking about the re-bop unsilanced aircleanerl. The base is also smaller in diameter to fit the smaller AFB. If I'm not mistaken the aircleaner base on the D/Dart was modified to fit the Holley carb.
