'65 273 Air Cleaner & Carb Linkage Wanted

It will be difficult to find an original 4-bbl. air cleaner for a Commando 273. The last one I saw for sale was listed at about $130 plus shipping. You can buy an adopter to fit a standard 5-1/8" air cleaner to a 4-7/32" carb throat that is the original carb. throat size for about $10 on e-bay. This is a molded plastic adaptor, aluminum versions cost about $20.
