Okay, the new 02 HD's have a two piece, is it possible to just snag a one piece from a regular supercrew?

 

Yes it is. Or you can get one from a 00 or 01 HD (both trucks are overall the same length) because they have lightweight aluminum driveshafts instead of a steel shaft of a regular truck. But if your gonna go for major MAJOR HP, maybe a steel one would be better cuz i've heard a couple L owners say they broke their aluminum driveshaft. But the aluminum one is still strong, its bigger around than the steel ones, and its still saves weight. (looks prettier too...no rust

 

Thanks for your help!
