9 inch & Drive Shaft Swap

Finally found a 9 inch rear for my 67 Mustang with a 289 / C4 it's out of a 69 Cougar, should be a straight bolt in.


Looks like it's been in a sand storm!


Here it is somewhat clean. You can see it's missing a nut on top and there are no washers under the nuts, but it's a 3.25 which is an improvement over my 2.75 8 inch.



Here's the problemwith the Mustang drive shaft, it's a 2 piece drive shaft with rubber in the middle and its got to go.

I'm pretty sure a shaft from a V8 Granada would work just fine after it was shortened to the right length as the Granada has the same C4 and an 8 or 9 inch rear. However there is a 408w in the coupes future and my question is are there any other easy choices for a drive shaft that would be beefier and still bolt right in with my 9 inch and C4 after it's shortened? First thought was a truck drive shaft but they use a slip joint thats built in to the shaft itself.
Full size car with C4 maybe? I think the Mustang uses a 1310 u-joint.

Thanks,

Morgan

First the 69 rear is 2 inches wider, wheel to wheel.

Second, Ford used the rubber 2 piece driveshaft even in the 427 cars.
Adapt to the larger u-joint, using the hybrid 1310/1320 joint, and a shorter yoke if needed and enjoy it as is. But install a drive shaft loop in any hot rod car.

Change the shaft later. You will probably need to make a 3 1/2 or 4 inch thick wall shaft with custom yokes.

Granada 9 inch cars had the bolt together flat flange yoke at the rear same as the Versailles. 8 inch cars had conventional yokes.

I have put 8 inch Granada rears into Versailles cars when getting the disc brake rears out then sold the Versailles.

Re: 9 inch & drive shaft swap

Thanks for the reply, must be a slow day on the board as this post is almost 2 weeks old and no one replied to it till now. Guess no one was interested in my trying to get by on the cheap instead of just getting a custom shaft made. Oh well, I'll figure something out I'm sure.

Still don't want that 2 piece drive shaft.

The Granada 8 inch shaft was what I was thinking. It won't be any stronger but it will be a match I think.

The Cougar 9 inch is the same and will bolt right in.

BTW this is what I have about Mustang rear ends:

1. 1965-1966 Mustang 8 & 9-inch housing width: 52".

2. 1967-1970 Mustang 8 & 9-inch housing width: 54".

3. 1971-1973 Mustang 8 & 9-inch housing width: 56".

4. 1957-1959 Ford big-cars 9-inch housing width: 52".

5. 1960 model T-Bird 9-inch housing width: 52".

6. 1975-1980 Granada/Monarch 8 & 9-inch housing width: 52"

7. 1977-1980 Lincoln Versailles 9-inch housing width: 52"

8. *1957-1972 Ford pickup 9-inch housing width: 56"

9. 1973-1979 Ford pickup 9-inch housing width: 59"

10. 1980-1985 Ford pickup 9-inch housing width:??

11. 1966-1977 Ford Bronco housing width: 52"

Thanks,

Morgan
