The AOD can be built fairly stout, and offers overdrive and a locking torque converter without all the electronics of the 4R70. The only tricky part is getting the throttle position cable set, if it's wrong the transmission will not live long.

Thousands of AOD swaps have been successfully done. Adjusting the throttle valve cable on the AOD is very simple.
This example shown on EFI intakes but, just imagine the end of the cable is attached to the butterfly shaft on a carburetor, if you're not using the EFI induction.
In reference to the 4R70W, the electronics of the shift solenoids are easily handled through a stand-alone shift controller. The transmission can be set to shift to factory specs or, it can be programed with altered pressure levels or shift points (alternate and selective 'performance' setting). It can work as a normal automatic or, it can be setup to be manually up and down shifted (such as with a paddle shifter) or, as a selective combination between fully automatic or manually shifted. The torque converter lockup can be selectively engaged or disengage at will. These features aren't possible with the AOD but, personally, I would still take the AOD over a heavy, non-overdriven FMX.

If your looking for a flex plate remember that for changed the imbalance on the 302 from 28oz to 50oz in the mid 1980's. This is important.

Use the flex plate that's on the engine now. The FMX should have the same T/C bolt pattern as an AOD T/C. Use new locking nuts though. Ford part number 378941-S441. Still available because Ford still uses the same nuts. Your local Ford Dealer will have them in stock.

Depends. The flexplate on that engine should be a 164 tooth. What is the FMX out of? Do you have the flexplate that was used with that FMX to count it's teeth?
