Hot Rods Need to identify rear differential?

Can anybody identify this rear differential? want to get a new chrome cover.

 

a few more larger pics from different angles will probably help a lot. It looks like a funky "cover" thing that someone stuck on the back, to make it sort of look a little like a quick change. But if the gears and stuff come out the front, maybe you'll discover that there is no removable cover on the thing, at all.

Also helps to know what car it's in.

So.....look more closely at it, see if you can figure it out. If not, get those pictures, but keep in mind we will want to see both the overall view from different side angles, from front and rear, and also maybe close ups of where the funky coover attaches to the housing.

 

Lets see if I can pull a rabbit out of a hat...Its a 55-59 chevy pick up , maybe Cameo with the spare tire holder showing behind diff...With the factory rear end and a funky diff cover????

 

Why don’t you just chrome that one ?
Or polish it ?

Maybe it’s just the camera angle, or maybe it’s just me, but it looks like excessive toe in on that vehicle also.

 

Watch these videos on differential cover design.
You don't want to use a flat back cover.
OEM covers are curved for a good reason.
Very interesting.

 

great info,, stay stock for me.

 

Good info there

 

Good to know ,thanks for sharing.

 

50's ford ?

 

I agree with Squirrel, appears to just be a decorative cover placed for looks. Get more shots showing sideways and front views and we can identify better.

 

Not unless it is a lowered pick up. Cars would be axle above the leaf springs.

 

That looks a whole lot like one of those fake quick changes that Phil Lovejoy cast and sold in the 80's or 90's that came with a steel ring that you welded to a 9 inch or other rear end with a drop out center section.

 

How many lug bolts hold the wheels on and what is the bolt pattern?

 

I ran that photo by my buddy who probably ran it past Phil and he confirmed it is one of the covers that Phil made in the 80's. He made those and two piece Chevy valve covers that he would cast the wording of your choice in the tops.
Depending on how much welding the did installing it you might be able to cut the welds and remove the ring after you unbolt the cover from the ring if you are so inclined.

 

I know the quick change cover is just for looks and fake. Lug is a 5 on 4.5" pattern. Engine tranny R Mopar so thinking took whole drive chain but Chrysler, Jeep, Ford all have that lug pattern in various yrs. It's been cleaned ground sanded and painted nicely but they removed all identifiers. I'll pull the cover & if I see no opening I'll just touch up where its bolted and leave it alone. Oil looks clean and once I cleaned up outside not much sign of where. If opened in rear, ill see numbers identifying.
thx

 

Can you post a picture of the 3rd member area from the front?

 

still waiting for those pictures

 

Sorry on more pic's. Me and the car R in two different places for a couple of weeks. will do when I get back to the car.

 

What a interesting video posted here.
That really opened my eyes to the larger square-back covers.

 

5 on 4.5 and spring over should narrow it down if the spring pads were'nt flipped. Maybe Ford Ranger.

 

If you take the cover off you will also have to figure how they welded the ring it bolts to on and see if it is viable to cut it off.

Always wondered why a 12 bolt diff. cover directed the lube towards the carrier bearing, and the 8.5 and 7.5 did not.

 

Sorry for delay, just getting back to car location. Here’s the additional pic’s from drive shaft side. Looks similar to a ford 9” don’t recognize the X on right side? What is it?

 

I believe that's an 8-3/4 Mopar. The 'X' denotes that it is the '741' type.

 

9 inch ford you can't get a socket on the bottom bolt

 

Not Ford at all, 8 or 9". Could be 8 3/4" crashler as suggested above.

 

741 Mopar makes sense, looks like original builder in '95 used a donor Mopar & used the 383ci engine, 727 Torque-Flite and Mopar rear, probably shortened the drive shaft & used it too. Now that I have an idea I went to https://www.hemmings.com/magazine/mus/2004/10/Mopar-8-3-4-inch-rear-ends/1280934.html and will look for the tag that supposed to be on it to ID the ratio.

 

Count turns to figure out the ratio. It's a MOPAR just because of the pinion snubber mounting holes.
