some of the salvage companies may be able to supply the part. you have to admit, its is quite old. maybe its time for a NEWER refrig. those can be found on the internet or at the salvage companies
colaws in carthage missouri, or arizona rv salvage are good places to start.
making your own parts is a good idea if you are sure to use the original sizes, and lengths. as far as the gas tube, size doesnt matter, as long it can be readapted to fit the original.
the fuel/air adjuster should be as close to original in shape and size
as possible.
