I do believe the wheel cylinder bolts are 1/4-20 x 1/2" long. If you have new ones you could take them to the hardware store and match them up. There should be a roll pin on the coupler at the steering box you have to knock out, then disconnect the shift linkage in the engine bay, go under the dash and disconnect the two connectors then there is a plate the bolts it to the dash and a few bolts at the floor board.
