If you have wrenches that fit the collet nut and hex on the forward drive shaft, it is not too difficult. Without good wrenches, the nut is hard to get to, likely requiring you to disconnect the parking brake cable and remove the transmision mount to lower the driveshaft. A 15 inch adjustable wrench will work on the nut, a 12 inch on the drive shaft. (A monkey wrench will work but not well.) Then it's a matter of six nuts and bolts on the rear flex disc, two bolts on the center support, assuming that you are not going to completely remove the driveshaft (ie: wire it up). Make sure to mark the driveshaft connections so that you can reinstall it in the original position. You will want to get at least one of the rear wheels off the ground so that you can rotate the driveshaft.
