Driveshafts

[Ziegelsteinfaust]

Last night at about midnight my driveshaft let loose. At this point I am not sure all of what happened, and I am working on that now. Non the less one of the axle caps was ripped off. I didn't get to bed till almost 3am, and I can hardly sleep past sun up.

But what is the recommend driveshaft style or upgrades I can do to a 83 C10 rcsb with a 450-475 hp 383 engine. The truck has what appears to be a truck 12 bolt axle.

Should I go for chromoly since steel is stronger, or aluminum since alot of performance versions are made of it? I am not opposed to carbon fiber, but I am not sure if my proposed axle swap will work with it. As with steel or aluminum they can reshortened if needed.

Since I am sure I am going to lower the truck. What is the recommendation on shorter driveshafts for a 4/6 drop?
