A surprise find today! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**Grumpy old man** · 08-15-2018, 03:46 PM

Braking down a long bed parts frame for some pieces I need and part out the rest I pulled the rear differential cover and found this POSI ! Clean gear oil and turns like butter, Yeah !

No, It's not for sale ...

Very nice. What's the ratio?

**clay68c10** · 08-15-2018, 04:08 PM

That is a nice find. I'd be hoping for 3.73

**old51sedan** · 08-15-2018, 04:11 PM

Nice!

**Stocker** · 08-15-2018, 06:49 PM

Some days it's better to be lucky than good, eh? Nice find!

Wish I could get that lucky, nice score.

Always nice to be surprised!

My surprise comes when I open a bucket and I see a posi diff in there. Hmmm... which one is this and when did I put it there?

That's nice, now look at the filler plug, posi should have a round filler plug that sticks out. The round plug held the red tag stating to use posi additive.

Over 45 -50 years the Red Posi tag could get lost, especially if the PO exposed the truck to JiffyLube type maintenance,

Agreed on loosing the tag but the round plug is usually still there. Non posi plugs are flush and don't have the raised round stickout.

I was pleasantly suprised when the roller 1969 C10 frame I bought ended up having a factory Posi-traction unit and 3.73's in it.

There was no tag , After 51 years who knows what happened to it over the years ? I have to say I didn't even look for one at the time , I dug through my parts bins and it has a new one now.

Funny, I never noticed they had round plugs.
