olcking rear diff

I have a 1976 F350 super camper special and it has a Dana 70 35 spline rear end with 3.73 gears. I'd like to install a limited slip carrier in it. Can a posi carrier from a dodge rear end work if the dodge used a dana 70 rear end? If not, does anyone have a suggestion as to where I can buy one?

What is the AXLE code stamped on the Warranty Plate? It's on the 2nd line-far right.

Warranty Plate riveted to the left door face below the latch.

I wanted to verify that your truck did not already have optional Limited Slip.

B9TZ-4880-B .. Limited Slip Kit / Obsolete

MCDONALD OBSOLETE PARTS in Rockport IN has 1 = 812-359-4965.

CARPENTER NOS OBSOLETE PARTS in Concord NC has 1 = 800-476-9653.

What parts are you saying are different? The part number I posted is for the dealer installed kit.

He's wanting to put the limited slip carrier in his housing. He'll reuse his ring & pinion & bearings … and he'll have to set them up too … but he'll need all in that picture, carrier, clutches, spider gears, etc. That "4880 kit" looks to be just the internal wear items.

Why not?

This illustration shows the "No Limited Slip" differential & gives notes to the locking differential illustration that you posted.
There's no pic that shows all the parts plus the L/S parts. The only pic that shows the L/S parts is the one I posted.

The 9's that came without L/S had a dealer installed kit to install it, it came with everything needed including the gear oil and additive.

So why wouldn't this Dana 70 kit have everything?

The OP needs to post up the Dana BOM number of the axle, then we can verify what offset the carrier is. The kit above is the clutch service kit and won't work for the OP.

I'm not sure I completely understand, but if the "BOM" number is necessary, where would I find that?

I don't need the BOM number. You gave me the AXLE code, that's all I needed, and...

I only wanted it to verify that your Stupor Camper Special did not have Limited Slip, as it was an option.

Pic: See B9TZ-4880-B in column right towards the bottom of the page.

The B9TZ-4880-B is still just the clutch kit for the L/S carrier. The OP will need a new carrier and set up the gears again for the swap. There is different carrier offsets so I told the OP to post up the BOM.
