The only drawing remaining in the system carries the -B3 suffix, which I presume to point to one supplier, drawn in 1944 and last revised in 1946. Material specified is Aluminum, Ford material code "M1588 or equivalent". 9N-12130-B3 (shown on same dwg) was the assembly with the bushing installed and burnished to .8635/.8640 dia.
