I own a '73 FJ-40 and want to go with disc brakes all around. At the same time I want to up grade to a full floater rear end. For the front axle, does anybody know the best way to approach this. As I understand it, there is a kit available that includes everything including the outer axles. I guess they need to be replaced... is this correct? My other option would be to find a good buy on a newer front axle with disc brakes intact. For the rear axle, did the full floater come with disc brakes in later years? IF not, is there a kit available for the conversion? Thanks for any help you can give me.
