I know I can go to disc brakes on all 4corners but then I loose the E-brake as I will also be replacing the transmission ans transfer-case. So I have heard about 10" and 11" rear brakes but have only found 11" one so far and no parking brake setup.
If I did the rear disc brakes I could go with a Manual Caliper for a parking brake on each rotor or a hydraulic caliper like Total Performance did on there T-Buckets that mount to the rearend.
