You need the entire LS1 backing plate. The LT1 car incorporate the emergency brake into the caliper. The LS1 style uses a "drum brake" style emergency brake.

There really isn't much to be gained performane wise from the switch, the lt1 rears are pretty good as is. From what I've read about them it's quite a pita to make the switch as well. Only reason I could see to do it is for visual, the ls1's have a slightly larger rotor. I'm switching to LS1 fronts now but didn't see a reason to do rears.
