Default Need a differential

Hey I blew my differential on my '84 automatic. ratio 307. My mechanic is having trouble finding one. I can find the bearing kits and the crown & pinion parts online but not a whole diff.

Any line on where I can get one?

The shipping is gonna be a killer.

What parts are you looking to get for your Dana 36? Are you looking for a loaded pumpkin or the carrier?

Thanks

You DO NOT want a known '84 D36 3.07. Early '84 D36 were known to be differentials with problems and upon repair required different internals. You want a D36 that's '85 or newer with the 3.07. Using car-part I saw a potential 3.07 but it didn't stipulate D36 auto. A 3.07 D36 usually brings a premium price. I would think they're out there. Scarce and a premium price I'd think.

2 teeth are broken on the crown. I think that's the extent of the damage. Was hoping to get a whole new diff but proving impossible to find. Might have to repair / rebuild. I can find the bearings and seal kits but can't find the 3.07 gears. Open to either the parts or a whole diff.

Did you try the one I mentioned using car-part? Yours is apart and 'on the bench'?

I found several in Canada - the 3.07 is still showing but there's no mention of if D36 or D44 - just it's an '87. None of the others mentioned ratio. This one did and using my selection it very well should have chosen AUTO so D36.

LOOK FOR REAR AXLE and choose non interchange years.(I chose '87 - '95 I believe) There was many !!

Did you find the one that mentions 3.07- you need to understand that many are likely pricing these based on the assumption people are interested in them for 'hot rod' builds. There's maybe many options. I

He says it came from an 84 but it was manual. Is the diff the same if it was from a manual or automatic? 3.07 all the same?

All '84 were D36

JUST REMEMBER - YOU DO NOT WANT ONE FROM AN '84 UNLESS it's very late and you can confirm it's the later carrier and short axles!!
