You are going to have to measure for this one as even small differences can create problems. Simply measure the length of your driveshaft then measure the distance from the forward portion of the transfer-case's tail-section dust shield and subtract the two values.

It is my opinion that it is best to cut the portion of the shaft behind the carier bearing, closer to the rear differential.

if you cut the side closer to the rear diff make sure the driveshaft angle is not to steep going into the rear diff. it will lead to constant u joint failure

Do not cut the back, you will not be able to mount the rear carrier bearing if you do. Stick with the front shaft.

The rear carrier bearing can be eliminated if the rear portion is elongated.

Are you talking about combining the 2 rear shafts? Cause that wouldn't work either, critical velocity and u-joint angle problems (you could probably get the angles worked out but not the C V). If anyone wants a 2 piece shaft that will work, one off an awd expo/summit is perfect. That is what I'm switching to from the dsm shaft. It's about twice the diameter but half the weight with only one carrier bearing.

Sure, it may not be perfect but it worked and still does, as far as I know, on the black AWD GT I owned.

I prefer cutting the front, because the floor of the car seems perfectly set up for the bearings to mount that way, and the you don't have to re-invent the driveshaft. Anytime you lengthen a driveshaft section, you should also increase the diameter of the tube to retain strength, and the ability to maintain integrity at high RPM.

Here's a shot of the guys shaft who tried to go one piece:
