"How long did the 1923 ARA boxcars survive until they were retired?
1940? 1950? 1960+?"
Generally, very large numbers of these cars remained in service until
the mid-to-late 1950s, when they began to be retired in large numbers;
however, they would still be evident through the 1960s, particularly
PRR Class X29 express service boxcars, which stayed in service until
the mail contracts were finally lost. Check period ORERs for service
data for specific owners.

None that I know of, barring any secondhand owners.
