The 1941 parts book lists a leather boot for linkage for 1939 only. The 1940--1948 completely revised linkage lists the two piece stamped metal boot.. The illustration for 1939 shows the boot but difficult to determine just what it looks liike. It looks like it goes just forward of the vacuum cylinder. The linkage it covers is quite a long span from the cylinder linkage below to the transmission lever above. The shop manaul picture is a little better but still not too clear.
My Pontiac parts book only goes up to 1937.
