I have a 2004 Duramax for sale. Long story short it was a work truck, used it for parts to replace the front end of another truck, and now the rest of it is good for parts. Has complete drivetrain (engine exposed to rain), Allison transmission is good, still has turbo, has a good axle and other parts. Asking $1000 obo. Have a bill of sale. Not parting out I’ll also fill the bed with some scrap metal if you plan on taking parts off of it and scrapping it.
