I have a 57-61 chevy 10 bolt rear. It has 3725899 casting number and BB stamped on one of the axle tubes. I have it in my 23 T Bucket. I want to convert it to disc brakes and change the gear and carrier to a LSD. Can anyone point me in the right direction? I cannot find much info out on it, like is it a 8.5" rear, what spline, etc. Thanks.
