Replacing rear main oil seal

Need to replace my rear main oil seal. It will be my first time for such a job on this vehicle ('99 6.5 turbo diesel Chevy 3500). Can anybody point me to a start to finish procedure? Video would be great. I looked around here, but didn't see anything.

Likely the easiest is to remove the rear drive shaft and the shaft to the front diff. if it is 4x4. 6 bolts on the lower Bell housing as well as the brace between the passenger engine mount and that lower bell housing have to be removed. 6 bolts have to be removed from the flex plate (auto trans) and torque converter. Slide the trans. back, then remove 6 bolts from the flex pate to the crankshaft. Then remove the flex plate.

I have never had to go beyond this, as the rest was a complete rebuild, I suspect a screw would have to be inserted into the seal so it could be pulled out. There is a special install tool recommended for the seal which I have never used either.
