axle ID

[Blue85]

Looking on marketplace and the guy doesn't know what he has. I'm pretty sure the rear is a 9.5" GM, and I am looking for a pair of 8-lug axleshafts, so that should help me. On the left, it's 8-lug, but is it 10b or D44? I'm trying to swap my front from from 6-lug to 8-lug, so I think this has what I need no matter what. I really just need rotors and backing plates, and calipers are maybe optional, but this has new rotors and calipers. I can keep my existing D44 knuckles and 10b spindles. I also have a set of 8-lug hubs already, so even if this is the early small bearing D44, I think it's OK.

Hard to tell with the potato photo the guy gave you.
Brake hardware looks later, but also looks replaced

Kinda looks Dana, don’t see the ears on the top
Tie rod from the bottom is later

AFAIR, the bearings are different size but the hubs are machined internally the same. Maybe someone can confirm
Edit hubs and spindles are machined the same for an years I think

Since it’s got the tie rod under the knuckles and a 9.5 14 bolt and they are a matched set, I’m gonna bet it’s a ten bolt but it will have what you need.

I was thinking that the 9.5" came about after they stopped using D44, but who knows what's been swapped over the last 40 years. Also, just because he thinks they came from the same truck doesn't really mean they did.

The large flat strengthening rib on the pinion passenger side of the housing suggests 10Bolt.
