Hello Everyone,

 

My truck's two piece rear driveshaft was very worn after 172,000 miles (doh), so after speaking with a couple of driveline shops I selected one to build me a one-piece aluminum to replace the two piece.  The shop required u joint size confirmation so after pulling the rear u joint straps, i measured the caps/width & came up with 1410 ujoints.  The shop didn't seem phased that i had 1410 u joints (said could have 1350 or 1410) but surprised since I thought all D70's were 1350.

 

I continued my investigation and  after more web research concluded I may have a D80 Hybrid (like the manual trucks) based on the diff cover bolt pattern.  The ID tag doesn't say so maybe someone can shed some insight?  While some will prob say "no way" i did find some threads on the net of claiming D80 hybrids in auto powered truck but nothing conclusive.

 

The truck i own did come from the factory ordered with the heavy duty package (suspension & drivetrain/241DHD trans) along with the camper package.  Could someone post a picture of your D80 hybrid for me to confirm?

Series #, so much for it being  measurement. Thanks for the education.

Mine was 720 shipped from driveshaft specialties in tx.  

 

I could have done better locally, but i was living out of state at the time.

They are my go-to unless I can find something lower in price.  I've heard good things about their products.

I didn't have any issues with them.  Great service all the way.  I would use them again. 

 

I did end up getting it shortened for the D70-80 swap I did, and found a great local shop that probably could have come in a bit cheaper as I could have reused my old yoke and no shipping.

Do you mind saying what they quoted you?  I'm interested in doing the same for mine...trying to get an idea what the ballpark will be.

 

I was quoted $600.00 shipped for a aluminum rated to 650hp which is beyond my needs.

The one piece driveshaft should arrive next week, will take some photos of comparison between during install for posting.
