[6600DURAMAX]

Finally decided to post my build thread.

71 4x4 Crewcab Longbed with Duramax/Allison Power Train

Cab is currently at the body shop getting the extension treatment. Hope to have it back by May or so.

Just picked up a 2002 Duramax for powertrain, interior, etc..

Have a couple immediate questions

1. Should I use a factory 71 Chevy 4x4 Frame and just extend it. Worried about the strength? Could box the entire frame. Using that frame would require building all new mounts for everything.

2. Use a 2001 or newer HD frame, everything would bolt in and just re-do the cab mounts. Am really worried about how much of the frame would be seen as those trucks seem to have a ton of frame showing below the cab and it looks like crap. Maybe I could lower the cab as mush as possible.

3. Couldn't I use the 2002 factory wiring harness and just splice in everything, lights, etc..... Plan on using the factory dash, steering column etc..

Any one have any pics of these bodystyles on newer frames
