Looking for 19.5” 5-lug wheels

[Chautauqua]

Hi
I'm not sure if this topic belongs in this specific forum category but it deals with Dodge frames so till try it...
I am looking for 6 "Budd" wheels for a 1949 Ford F5 truck size 19.5" with 5-lugs.  It appears that some Winnebago Class A motorhomes where built on the M-500 chassis from the 1960's to the late 1980's had these type/size wheels.  Any assistance you could provide would be very much appreciated!!
Thanks.

The latter, M600 series is the chassis which had the 19.5" x 6" with 6 lugs.
M500 had only 5 lugs.

Other than buying new at $$$ prices, RV salvage yards would be the place to look.
