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.

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!

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.

So according to him that means it's an 8". And if it still has the same gears as it did when it rolled off the assembly line 43 years ago, then I have a 3.00:1 RAR.

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?

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.

The retainer holds against the axle bearing, which is pressed on the axle. If the axle bearing separates, the axle can still come out... but it is likely you will feel a serious vibration or hear some ungodly noise warning you of this.

Yup! That can happen.

I put some small tack welds on the retainer (or collar) behind the bearing for extra safety.

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.

Sounds like you had the same setup that my car has.
