727 torque converter/pump bushing

my leak was originating from the front "some where" pump bolt seals/seal itself/pump housing seal ????been leaking since Ive owned it //new converter /leak warranted the re do ....bought a re seal kit and noticed a unfamiliar converter and this..

The pump gears show no ware/pitting or scoring on a 50 yr old trans / front band looked great also
