i've got a question about the brakes on my 46 merc.they are all cleaned up and ready to put together.my question is,is there a position that the bottom cam #91a-2028 should be in,meaning the cam washer has a 90*angle in it how should that point be indexed ? (12 oclock,3 oclock ect) i'm not sure that my brake parts are correct for a 46 but this all i got. thank you,
