Yea its very true its what i have for a diff, just don't use the axels,backing plates and drums, they hang way out for the full size car it was.
Stock axels fit this diff as for brakes i went to a 70 fairlane style for 10" backing plates to use with 10x2 shoes and drums,because i went to 5 bolts rims.

I'm running a 1959 Thunderbird 9" housing in my II, it's only 1" wider overall, but I had to swap the perches to make it work. The best part is, those T-birds had 11" drums.
A 1977-1980 Lincoln Versailles is a direct bolt-in. A Versailles is a pimped Granada which has practically the same rear suspension as a 74-78 II. The Monarch/Granada had 5 lug 8" rear ends. The Versailles had a 9" with rear disc brakes. Many had 2.50 rear axle ratio and you will want to change that unless your running on a dry lake

No, It's not.
That is, unless your lazy and accept less than the best ....
Even though the best is something you can do for yourself..
Seen this thread many times, tired of giving cluez.
Cluez being the proper vernacular..
Or is it Cluze, ?
No matter, I doubt any one could document the Genus of the 9" anyway. ... other than my memory and, hell, whats that worth.?
:]

Thanks.
I thought it more like 3/8 per side (Granada, Monarch, Versailles) but then theres that memory thing.
When the springs are hanging it's real easy to bolt the springs to the axle because of flex in the eyes and no metals truly rigid.
When the cars on the ground the springs go into a bind. The spring mount is ~ 3.1" and the springs ~ 2.6" gives the spring 1/4 inch clearance per side. Kick the spring out 1/4 inch and the eye is right on the mount. Or it should be.
If the 9 is installed only for Ooooo factor then I guess keeping the rubber works. OTOH if there is a need for the 9 ditch the rubbers and get a set of CE (ie) perches for 3" tubes. $20 bucks from Summit.

The Versailles 9" has discs that are very expensive to replace/repair and are much heavier than the 8" rears. Also the E-brake cable has to be altered to work. The II uses an oblong holed mounting plate and matching perches. The Granada/Versaille uses the regular pin style. Another reason to swap perches if you're considering a different rear.
Most Granada's had the 8" with 10x2 1/2" drums- a nice improvement over the stock II setup. Some Granadas that had the V8 engine came with the 9". All Versaille came with a 9". One benefit to the Granada rear axle swap is having larger axle bearings. This increases the lifespan of the bearings.
This dude has a 9" Versailles rear axle in his 1978 King Cobra. In the artical in the Magazine he quoted "bolt in" . he spiced the II parking brake cable to the Versilles cable with hardware store cable clamps. I supose his "bolt-in" has theoretical spring bind. Do you really think that in this instance the performance of the rear suspension would be compromised I personally think the flexibility built into a leaf spring suspension could tolerate the pearchs being a little off.

Do I detect a note of hostility?

You Think? ??
Oh man, don't say that. I measured and measured again and kept coming up with a 1/4 so that's where I put it. Now you got me thinking if there's a chance I didn't get it right when I put it in my 74.Wart said:
I had a 302 Granada given to me so figured what the hey I might as well use the rear too.
Anyway I had rather use my 74 as my guinea pig, that way it gets done right when I do my 77.
mustang2 said:
The only things I will swear I know about the '74s are 1) they were the IIs first year, 2) they had a longer header panel, and 3) the fuel cap is below the seam.
Could be 1/4.
You measured 1/4, I measured around 3/8 (my notes on this are long gone), lets go with Sleepers 5/16.
I would say 1/16 is the 'little off' that's not going to matter a whole lot, if any. The bushings will get use to it.
But the Goober with a KC who hacked and cobbled the rear into his car?
And the cable clamps didn't tip you off to anything?
True, a little crude
I would probably do the same though, I only ever use the parking brake durring the safety inspection (on automatic cars). It is kinda scary how pencil thin a parking pin is though
Do I detect a note of hostility? Nope hostility is your bag, I like to try to help people.
You Think? ??[/QUOTE] All the time
Have you actually trial fit a Verailles rear axle in a II??

Dangerous.
And a big red flag and klaxton indicating and warning of hack work.
Hmmm .......
Until you need it, then it's too late to do it right.

Actually the 3/16 (?) pin is overkill, once shear is understood.

Sometimes bad information is worse than none.
I think the question is, have you installed any housing other than a IIs housing in a II??
You first, then I'll answer you question.

I guess, but the propotioning valve re-directs brake fluid in case of a line failure. What state of dis-repair would lead to actually needing a E-brake. Pulling the parking brake lever is fun. the import dudes call it drifting.
Actually the 3/16 (?) pin is overkill, once shear is understood. Are you an engineer? My dad is a automotive engineer, and I argue with him all the time too.

I didn't know the information was bad, lucky you were here to stick it to me, I mean help. Don't believe everthing you read I supose
I think the question is, have you installed any housing other than a IIs housing in a II?? I could not help but notice that you always answer a question with a question, purhaps your a politition and not an engineer as preveously thought

Uncle, yours is bigger-this time. Automotive trivial pursuit is my favorite game we will meet again

Your already down by two, at least.
Should stop while your only that far behind.

We are just out of the staging beams and I still have two stages of nitrous
Thanks for exposing your attitude and intentions for all to see.
No secret I'm adversarial, now we all know you are too. You can deny it, again, but we all now know better.
Pick your races wisely, Grasshopper.
