The 174000 series cars were "assigned" to Pacemaker service. When they were removed from Pacemaker service, they were renumbered by changing the "4" to a "5". There is at least one picture extant that shows the "5" as obviously the only altered number on the CASO website - a quick and minimal renumbering job if there ever was one!
So the 175000 cars are just renumbered 174000 cars. At the same time, most if not all of them had the light "cushion" springs from their "LCL" assignment days replaced with regular springs so they would be available in the general boxcar pool.
