spindle question
really i don't know why they asked where the caliber was mounted because stock they were in front of the wheel.. you can swap the spindle from side to side to make the caliber rear mount but that shouldn't say that in any part books.
yes you'll need the bearing and seals, the MC just get one for a 73 disc brake duster/dart. brake lines are easy enough to make yourself if your talking about the steel ones that go from the master cly to the proportioning valve.. the rubber lines you can buy at the parts store... you'll need the disc brake proportioning valve or an adjustable one too.
