Don't know what spindles are that's on it. Or if they are the right ones. Someone else put it together(what a Laugh). So I'm out on a limb here. All I know is that it takes a GM rotor and caliper. Had to replace all that too. Sorry, it took so long getting back. Ordered a long block ( because the motor was such a great one and ran so great) ,(another laugh)started putting it in and had to pull it because it had 2 different heads on it. Great quality control? Not been a good 5 days!
