AOD's in (mostly) crown vics, town cars, and some
light trucks have a 1" longer tailshaft & housing.
The T-Bird stuff should be the same as the Stang
incl the throttle valve cable and throttle cable at
least if the TBird is a V8, you'd have to measure
length if it's a V6.
Some people have been able just to switch the
outer tailshaft housing without messing with the
shaft & have had no problems with their existing
driveshaft for length.
Also, AOD's other than Mustangs have a lower rpm
governor, which you can access by removing the
tailshaft housing.
Also there are some minor differences in the valve
bodies which can be cured by a decent shift kit
like
www.becontrols.com (Baumann) which is
good to do anyway.
The ones without a throttle valve cable are the
electronic versions like AOD/E and 4R70W.
The throttle valve cables for V8 cars that have a
similar intake and throttle body setup should
all be the same length, as should the converter
cover plate.
