Drive shaft length

[Ironman03R]

I need a 4X4 crew cab Auto (E4OD) drive shaft for a LONG bed. Does anyone know if the shafts are the same length from the carrier bearing back? What I'm asking is, Can I just find the front section from a F350 4X4 and use it on mine?
Does anyone have one they are willing to part with?

My observation is that the distance from the carrier bearing to the rear axle is the same on all crew cab or extended cab trucks.

The only difference is in the couple shaft. Mel is right on. I think a 150 might work if the ujoints are the same.

So anyone have a front half for a Crew Cab 4X4?
