Dana 44 locking hubs?

[bigndn]

I have a neighbor who bought a '72 GMC pickup. Evidently a PO swapped in a Dana 44. He says one of his hubs is failing. I told him to take the locking hub assy off and count the splines to be able to order the correct locking hub.

What's the easiest way to make sure this is truly a Dana 44 and find out what it came off?

edit: I posted this in HC because I figured it would get the fastest responses here. Thanks

Scratch it.

We fingered it out.....

all gm & ford dana 44's have 19 spline outers.
