D44-Open vs. closed knuckle ?'s - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Wanting to know if the guts from a closed knuckle D44(1968) will fit an open knuckle housing(1971)? I've got an empty open knuckle housing and wondered if I could take the internals from my '68 and put in it. Let me know.
thanks,
Matthew

the carrier and gears will. not sure on the axleshafts...they may be different lengths, but I am wanting to say no for some reason.

I believe they axle u-joints are different as well as the outer shafts.

Thanks for the replys. I was kinda thinking like 1969GMC but couldn't think of why. I've got the shafts out of a '71 so it might just work.
Thanks ,
Matthew
