As a ‘74 your car should have the later drum spindles and the large ball joint UCA’s. The easiest way to tell is to measure the ball joint flat to flat, the LBJ’s take a larger socket. I don’t remember the size off the top of my head but I’m sure it’s posted here somewhere.
Those factory 11 3/4” disks will outstop those cute little wilwoods everyday all day. And don’t let anyone with front runners tell you different. You want to really test some braking power run 275’s up front.
