10b and 44 spindles and inner bearings are subtly different. You can bolt the outers from either to either knuckle, but you need to match the bearings to the spindle. I lost a weekend over this one. I would just source the whole set of outers from a single year and not mix and match if possible.



There is. It's called the brakes that are on it, service parts still readily available at most every parts store. I'm no longer sure what you're asking. Did you get a drum brake axle you want to convert to discs? You said they're discs, but also that you "don't know a lot."

Or are you concerned about matching up the hydraulics? Best to do that by cutting off the metric bubble flare at the hard line and redoing it with a SAE double flare to fit the Chevy soft line. There may be a soft line out there that goes metric to SAE, but I don't know where to tell you to get it.
