340 aircleaner

Thx for the answers!
I have been thinking about which alternative is the coolest , use a orginal cleaner on a engine thats not matchingand not the a 72, or put the 70-71 aircleaner there instead because it´s much more nice looking ? :)

Found a good site that explains aircleaners

//Update//
The site tells me that the double snorkel -72 setup is from a 400 and the single snorkel from -72 340 :)
