359 air cleaner coupler

Are you asking about the part my little yellow chicken scratch arrow is pointing to?
If so I do not know of an aftermarket source other than Pete or a junk yard. They may exist but I have not seen one at a chrome shop either and that would be cool.
AutoCar and White-Western Star used one very similar if not the same. It may have been a Donaldson or Vortox supplied part and not a Pete specific thing.

 

I guessing your best bet it to make one yourself or to make a cardboard template and take it to a local fabrication or bodyshop and have them make you replace ones. I did see 4 states truck has replacement panels that attach to the cab.

These?

 

I found that pic online from a parts yard selling the complete cab as pictured. If the cabs are in that good of shape not to many places well part it out. Worth more complete. Courtland Truck Works in CA. may have one but they may not want to part out a good cab either if they can use it to complete another restorable chassis. Doors are getting hard to find without a cab attached these days.

 

Are missing it entirely or are you just trying to score another one to make a single into a dual breather?
