Re: 14 bolt conversion to disc questions/options

Can I buy just the bracket for the calipers and rotor, or do I need to buy a kit?

Are there any other options for a parking brake? All the kits want to add $200 for the parking brake calipers. Are there parking brake calipers from other cars that would work?

When’d did the rear ends (3/4 ton) start getting disc brakes? 1999?

Any help would be greatly appreciated. I’m sure there must be somebody out there that has done this.
The GMT800 2500HD had 14bolt AAM full floating axle with rear disc brakes. They have full two shoe drum parking brake inside the disc brake hat.
The semi floating 9.5" 14bolts are lighter duty all the way around. They have the same ring shoe parking brake friction liner as my 2009 Impala.
I believe The AAM 10.5" rear disc setup was installed from 2003-06 but it might've been a few years earlier.
