a buddy gave me this 9 inch. it's got the big bearings and a nodular case with 3.50 open gears and 28 spline axles. I'm gonna put a $40 ebay mini spool in it and see what it'll do before I throw down for nice axles and a locker. I am still researching cheap disc brake options, without much luck. If you know of any let me know. I do not need a parking brake btw.
