A Body Disc Brake Swap 101

the spindles look kinda strange on the 73 up disc cars. sometimes it seems like they are leaning forward. the design makes your eyes trick you. unlike the drum spindles which are just vertical. I devised a tool to check caster. It is like a bridge that spans both ball joints and buts up against the grease zerks. this along with a cheap angle finder gives a good ballpark figure of the caster angle. Make sure your car is level when you set the caster {or at the same rake as it is when you are driving it}
