 I have ordered the adapter kit ... bought a 1988 Mustang AOD that am having rebuilt ... should have it in the thunderbird in 3 or 4 weeks. If anyone has any input for me please let me know .

Greg, Everything in perspective. Before deciding on a ratio, what is the diameter of the tyres you are running/planning to run. You can work out the RPM's at road speed based on the diameter of wheels and tyres, the diff ratio and the outputof the gearbox (0.67). The AOD is basically a FMX with a OD. The advantage is that if you have decent dia wheels and tyres you can have a Low ratio (high numerically) diff for acceleration but still have low RPM at road speed for longitivity and fuel economy. I'm planning on using an AOD (a long term Goal) but I will retain the 4.00-1 rear but I run 2.2 meter Dia tyres. 2200rpm at 100km/h (60mph ish) Cheers grizzly, i,m interested in how you would use 2.2 meter dia tyres?,

I haven't tried it, but I'm pretty sure an AODE WOULD NOT fit in a bird, UNLESS you cut out the x member AND the tunnel and started over. There just isn't Much room underneath one of the birds. I would love it if someone could prove otherwise. Cause i've been wrong before.  Tbird guys don't have all the luxury of space of full size and pickup owners.  It would be the same for an AODE or an AOD, right? (they're physically the same size case?) Yeah. In my F-600, I have a LOT of ROOM (2 driveshafts too!!)

The main reason for installing AOD was crusing down the highway at 70 mph, to take some rpm off the engine ... the gas mileage was extra ...

If you are trying to help fuel mileage, you can have the gear ratio changed in the housing that you have without the wholesale changeover of a 9". If you want to improve mileage easiest, get rid of the dual carbs! Just sayin' that's the main fuel issue. Hard to have that cake and eat it too!

2.70:1 ratio is a bit on the low side for an overdrive behind the Y. 3.25:1 would be a better choice in that the engine will be in a rpm band that’s higher in torque and where better fuel economy will result.

I was told to consider a 9" rear end and a 3rd member at or about 2.70 ratio. What do yall think about that ideal?
