try this site:

According to these folks the Granada got the 8 incher from 75-79, and the 7.5 incher from 80 through balance out.
You misquoted them. The 7.5 from 81 on.

The 70s Granada series cars through 1980 model year are an extension of the 66 Fairlane/Falcon/Mustang unibody cars with much in common with all the other unibody Fords. The rear ends are on leaf springs and share direct interchangeability with most leaf spring Fords from the mid 50s through 80. The 81 on Granada is a Fox chassis car with coil/link rear suspension and strut front suspension.

The leaf spring unibody cars used the 8, 9, and this 8.7 inch rear end in 78-80 according to the data.

Weeeeeeeeell. OK........

If that is the is unique and.... it sure as heck is NOT an 8.8

I stand corrected.

Now I have to figure out where that 8.8 in that Granada from. Is the Ranger 8.8 a bolt in?

Thank you for the information.

All I am trying to confirm is if the 8.7 and the 8.8 that look externally identical have any interchangeable parts, and if the 8.7 was used in any other vehicles besides the G/M twins.

The WER-AA / AB / AC rearends of 78-79-80 look identical to an 8.8.

All that number data schtuff is worthless beyond telling us it is an 8.7.
I started to reply to this the other day at work, but got busy. As of Saturday (surprise!!!) I don't work at a Ford Dealership anymore, so I can no longer answer this definitively.

This information seems to back me up..

My recollections (although they are admittedly somewhat fuzzy) are that the WER was a different animal from an 8.8, and was only used for a few years, as stated above. WER's were only used in Granada/Monarch, Full-sized Ford/Merc passenger, and possibly Lincoln Versailles ...

The WER also seem to be obscure enough that parts are not available through places like Superior Axle

As far as parts interchangablity goes, I don't recall that either. I would expect that the crown/pinion would be different, although the cases, side gears, spider gears and shafts may be the same?

I also believe that the WER was offered as a conventional (non-locking) diff only.

Why do I remember this stuff? Because I got "stung" ordering the wrong parts occasionally. "Oh crap ... does the tag on the diff happen to start with WER?"

As far as WER's looking "identical" to 8.8's ... no I don't think so. Both of them were non-removable carrier style with a cover on the back, but I think the WER had a "squattier" oval shape. Uh-huh ... they were different.

"WER" --- 8.7" R/G
Gasket: Victor # P18561 10 holes, 11-5/8" x 11"

"WDR / WFL" --- 8.8" ring gear 1985 F150
Gasket: Victor # P27608TC 10 holes 10-9/16" x 11"

We had 3 Granada's/Monarch's with 9" pig style rearends in them. The thing that seemed consistent in all three of these cars were that they were 1980, 250 straight six, with an automatic, and called out a 2.47 gear on the door tag. This always made me think that at one point getting the 9" was strictly based what gear ratio you ordered more then the drivetrain as we never saw them in 302 or 351 Granadas. This rearend was 1" overall wider from backing plate to backing plate compared to a Maverick (that was what we were always messing with). This is all personal observation - not claiming any of it to be fact.
IIRC the 9" was the only axle available in 1980. The 8" went out of production in 1979, some of the floor space and equipment was being converted for either 7.5" or 8.8" (I forget now which).

8.8 Granada update

part # 19605-010
Ford Car/Truck:
1979 ~ Present
10 bolt cover
8.80 diameter gear
28 T rear axle

Eaton says there was an 8.8 Ford rear end used in 79-80.

I still believe I had one in an 80 Monarch (Granada)/ leaf spring car.

edited= Granted the 8.7 and 8.8 don't look alike.. I hunted down an 8.7 car a couple months ago so I would know for sure. I met one salvage yard guy who says they used 8.8 in the big car Vic line 79-80 on coils. Never saw one, yet.
