I got them at my local auto franchise, they sell them in the "HELP" brand section, with the rest of the bleeder screws in that section. The "HELP" brand calls them "ONE MAN JOB, BLEEDER SCREWS". They only have them in the two most popular sizes, 3/8"X24X1.25" and 5/16"X24X1.00", which just happens to be the bleeder screw size for XJ, front and rear.
