speedo gear/governor/rev limiter locations??

[1987cp]

Need something like the TransGo AOD-HP for it to shift into Fourth at WOT at any speed.

Typical parts stores will look at you weird if you ask for speedo gears, but your Ford dealer can get them (you get a 2 pack for about the cost of shipping one).

can get them at a lot of online parts places also, the are the same for mustangs...
