I'm not sure if the fmx flexplate is the same (needs to be 164 tooth and you will need the correct aod block plate) or the yoke (a c-4 or t-5 yoke works), 91 5.0 starter is fine, you will need a aod conversion crossmember, a conversion linkage or modify the stock one, you will need a lokar TV cable, throttle bracket(or make one) a 12 point aod trans bolt kit, a c4 tranny rear mount, unless the fmx is the exact same length as the aod you will have to modify your driveshaft. an aod diptube/dipstick assy. Get a pigtail off an aod car at a pick your part for the nuetral saftey switch/rev lights and wire to your existing wires, you will need to make new trans cooler lines to fit the AOD (5/16 or 3/8 steel line from any auto parts) if you dont have one put a good trans cooler on it.
depending on the carb you can make or buy a TV corrector bracket as the tv cable should move at a 1-1 ratio as the throttle and make sure the tv cable is adjusted correctly as you can fry an aod real easy, its better to be on the tight side to start than too loose.
you will need a toggle or push switch for OD and some wire.
Ron Morris/PATC and a few others sell the crossmembers and linkages, lokar can be bought from summit/jegs etc... just search for best price. TV correctors for holley an edelbrocks are about 15 bucks and available all over, TV correctors for demons are a little harder to find. All other stock parts either junkyard or or search the best price online.
What stall TQ converter did you get? lock up or non lockup?
I think there is a few pics of when I did mine.....
