1 piece driveshaft conversion

[toddtheodd]

Ok, so I know I can replace my 2 piece driveshaft for a one piece driveshaft in my long bed truck. (This would definitely fix my u-joints / carrier bearing problem)
What I need to know is what kind of conversions I need to do to get it to work.
Like how long does the driveshaft need to be? I know that I have the short nose turbo 350 transmission (I've checked into this before when checking into a 700r4 conversion).
Also, do I need to remove or cut the crossmember that the carrier bearing is in the middle of?

Basically, what kind of problems am I going to run into, and how do I get around them?
