Need help ID warn hubs

I have a set of new Warn hubs that wonder if anyone here recognizes.
The part # isn't helping me so far, #2550360(MoPar?)they are from a Dodge dealership. No Warn #s to be found. 19 spline 3/4 ton at least as I have a Dana-60 `85 in front of my Powerwagon and the bolt pattern is bigger yet. 8 bolts 5.5 center to center straight across.
They do come with instructions but no application Form# OM 1-1271(5M)

Thanks

those may be Dana 70 closed knuckle hubs. could also be for a 60's w300 too

I would give Quad 4x4 a call, very knowledgeable guys.

Wow that Quad4x4 site is cool thanks

Update
I called Warn and there #M72 for a Dodge W500 `57-72 or F500-750 Ford

There # is stamped in the knob.

Thanks for the help
