Driveshaft Conversion

[remote]

I Am stretching 1989 F-350 4x4 short base duelly by 24" to make into long wheelbase (161) inch wheelbase. Truck has one piece driveshaft coming out of transfer case to rear axle. What are the options of configuring the driveshaft? Remember after the stretch there will have to be a crossmember to support front of fuel tank?

Seems like a new driveshaft is in order. Most major cities have a company or two that deal in drivetrain components and can make driveshafts.

You can shorten a driveshaft that is in good condition, but lenghtening one isn't really feasible since it is more work than making a new one.

A dual driveshaft is technically possible using the original shaft and a new front shaft section, carrier bearing etc, but I'm not sure if there would be a benefit over a new single shaft....

My dually Crew Cab has the 2 section drive shaft with a center carrier bearing. If it ends up missing, I'll know who took it [img]/ubbthreads/images/graemlins/biggrin.gif[/img]. Hit the wrecking yards. OkieGringo
