Thanks to information provided by @Mark Gregush, I was able to purchase a glass sediment bowl filter for the 1930 - 31 Ford Model A from C W Moss Ford Parts. Made two minor modifications, first, enlarged the outlet hole to 5/8" to fit the gascolator housing and, second, trimed the outside seal on top of the filter, not necessary but it serves no purpose on this application.
The glass bowl gasket that came with the kit is too small for the gascolator and could not be used.
Still looking for a long arm gascolator. Have a short arm one for trade or will buy.
Picture of model - S, short arm gascolator.
