What do I have here? (Posi) - The 1947 - Present Chevrolet & GMC Truck Message Board Network

HuggerCST · 08-09-2006, 03:24 PM

It looks similar to a 12 bolt truck posi, but is a couple of inches wider, and has a few other small differences. Can anyone identify it?

I'm not real familiar with them but isn't that called a Gov-lock?

LUV2XCLR8 · 08-09-2006, 04:41 PM

Me either, but I think Asa is close

onetonk5 · 08-09-2006, 04:47 PM

I dont see the deal on the outside of the case that swings out to lock...or split the carrier in half.....that looks a lot like the clutch type posi in my 12 bolt.

Might be off a bit here . However; Looks similar to the M-1009 Blazer the military use. Thinking they were Dana 44 in the rear. My .02%

onetonk5 · 08-09-2006, 05:50 PM

im pretty sure chevy has never built a production truck with a 44 rear

HuggerCST · 08-10-2006, 10:26 PM

I don't think it's a gov lock. Could be the Dana I guess. ??? Here is a pic of it on the right compared to a 12 bolt '72 chevy 1/2 ton 4:11 posi on the left.

onetonk5 · 08-10-2006, 11:35 PM

Whats the spline count?Might help narrow it down.

There were quite a few leaf spring 1/2 ton 2wd with dana 44's in them . I have a 67 gmc rear in my 68 and it is a dana 44. I don't know if that is what the center section fits cause I have never opened mine up . If it is I would be very interested.

I think it looks like an Eaton unit with that thick ring gear back plate, but the single spring makes me not sure.

nevermind

BobbyK · 08-11-2006, 12:20 AM

This is a 12 bolt Gov-Loc.

And the other side.

HuggerCST · 11-28-2009, 08:22 PM

Ok this thing is still sitting around my shop and I still don't know what it fits. It is for 30 spline axles. I was told that it is from a chevy truck, but must be 3/4 ton? Any ideas?

Willys47 · 11-28-2009, 09:44 PM

maybe it's for a dana 60

292farmer · 11-28-2009, 10:49 PM

i saw an ED maybe its an Eaton Differential setup, like in some of the military cucv's? and in some 12 and 14 bolts?
