If you can get a deep well socket on the bottom two nuts on the pumpkin, it's an 8". If you need to use a wrench, it's a 9".

If you just get down and look under the rear of the car the back side of the housing on an 8" is one continuous sphere. A 9" have a bump out to clear the gear.
The center section of about any Ford 9" will work. Ford started using the 9" in 1957. I found a 9" N case Nodular Iron, in a 1969 Ford van. Works fine in our cars. There are different U joint sizes also.
Now you do have different axle bearing sizes in 9" and 28 or 31 spline axles. The housing from other cars will not work in ours you have to have correct width and correct spring mounts to fit.
You can get 35 spline 9" if you want a tough one.
I have a spare 9" located in North Carolina. Should be easy to find.
Go to a crusher yard get real cheap there if going to crusher and lots do.


When a man is in the woods and talks and no women are there is he still wrong??
