Disc brake upgrade

Thanks for that info 72bluNblu. Wheel clearance is not an issue. Running 15x7 Americans up front with a inside rim Dia. big enough to take Wilwoods largest rotor ( per their clearance chart ). Since it is a 74, assume my UCA's have the larger ball joints? along with the larger spindle wheel bearings? The ball joints are screw-ins, but I don't know how to prove they are the larger ones? Rear brake up-grade will happen down the road when I dump the 7 1/4 for an 8 3/4.

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.

:lol:Yes, trying to stop a "Land Yacht" at a tick under 130 was always - interesting. It did have LARGE factory brakes though.

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.
