I need to add more break fluid to the master cylinder on my 1946 CJ2a and am having a hard time removing let alone finding a tool that will actually fit inside that tiny round opening and will be able to twist the 1" square nut/cap off. Any help out there?

Ok I managed to get a digital camera inside and snapped a shot of the cap, it ended up not a 1" square nut, but rather a 1 1/8" 6 point, so I went and bought a 12 point 1 1/8" socket and a long handled 1/2" drives socket wrench, and with a little bit of a skinned knuckle I managed to get the cap off, used a simple self bleeder cup from local auto supply, and was successful on getting them bled. I am shocked no one posted any suggestions comments, or opinions, with 90 posts I would have imagined someone has done this before....

If you ever need a new cap and/or master cylinder try Napa Auto Parts. Those master cylinder were on forklifts many years since yours. You need to remove and compare/measure.
