|Smasher O'Brannan||I also (HAD) a 3.00 open diff. 8"incher in my 73' mustang that was replaced later in life by a nine inch. The best thing about having an 8" rear in a falcon/mustang/cougar is an 8.8 disc brake rear from an Explorer slides right on in!!......of course so does a 9".......The Explorer rear end is about a perfect match to the original width mustang rear as it gets. I have one under my wifes 66' coupe.|

Yup! That can happen.
I put some small tack welds on the retainer (or collar) behind the bearing for extra safety.

|John I.||Yes, they have retainer plates that bolt to the axle housing. One more thing that make a 9" better - if you break an axle, it stays in the car instead of letting the wheel loose to destroy your rear quarter or hurt somebody.|

One more dumb question while were at it..
How do you pull the axles in an 8" or 9" diff, since there is not a removable cover on the back? Are they retained by something near the wheel end of the housing?

Your just gonna have to get under there and try putting a ratchet and socket on those bottom nuts!

|AKB||Hard to tell about the bolts. If it helps any, the back cover is solid and smooth, with the drain plug slightly offset from the center of the cover.|

Probably an 8 inch.
If you can get a socket and ratchet on the two bottom bolts of the pumkin, it's a 8. If you can't and have to use a open or box end wrench, it's a 9. If it has a bolt on cover on the back, it's junk!

Really dumb question...
So how do I tell what size rearend my car has? I'm assuming it is still the stock rearend that came in my 289 equipped Fairlane 500 (whatever size that would be,) but I would still like to check. TIA.
