In the master cylinder rebuild kit (#805654) a different rubber boot is included. Does this one replace that one or does it go in a different place? Do I need both to rebuild my master cylinder. (1954 - CJ-3B)

These are just different style boots. You will only need one and if you buy the kit, the boot in the kit will be all you'll need. Thanks
