With the drop kit it should be close, but I still think it would need to be lengthened. Using a therom I learned in grade school, lets look at it this way. Asquared + Bsquared = Csquared. A = length of truck from trans to directly above where the driveshaft connects, B = length from the driveshaft connection up to the point just mentioned. C = your driveshaft.
If you increase A or B you will obviously have a different length needed for C. However there is leeway available in the driveshaft for a few inches increase or decrease for things like suspension travel, load bearing, etc... That coupled with the carrier drop kit should put it close, but I needed a longer driveshaft on my Mazda with only a 6" lift. It would work, until I got on it or spun the tires and then the rear would move under the torque and the driveshaft would pull out some and the splines would break. I think lengthening the driveshaft is a good idea. An even better idea is to get a once piece driveshaft but that's just me.
