I already have an Optima battery and if something does happen I can always go through the trunk if it ever becomes necessary. By the way this mod was not at all a hassle. It was pretty damn easy. Here are some pics of the differences in the handles.

This is the back of my front handle. Notice the harness coming off of it......it wont be used since all it does is unlocks the other doors.


This is the rear handle I got..........notice the brass/gold piece that is on the latch arm. It will have to have the rivet drilled out and this piece removed so the latch rod can pop in like it did on the front handle.

Here is where it needs to be drilled out

Also notice that the screw mounting holes on the back of the two handles are slightly different but all I had to do was bend the mounts on the door a little to make it work.
