The 1947 - Present Chevrolet & GMC Truck Message Board Network - View Single Post - this rear axle stuff is confusing, but I have to go posi

I read the numbers off my rear axle today. Here's what I found:

Axle stamp is HA 08 29W

casting number "looks" like: 8896888 with an N directly above that.

The center portion also has casted into it a "gm14" and an "H156"

Can anyone tell me what I have, and if it's not posi, what they think I might need to turn it into one? I'm mating this with an ls engine and a 4l80e trans.
