Hi 68, I just got done swapping an AOD into my 70 cougar. It was almost a bolt in. The site Steve sent covers it pretty good but I would add a couple things. first get the right trans, you need a trans from a 88 or later mustang because it has improved lube circuts and the right shift lever to match up with the early shifter. Gear ratio in the car it comes out of is also a concern because the output shafts on AOD's can have 7 or 8 teeth. You can't change the gear on the output shaft so the trans has to be tore down to replace the shaft. I am running 3:73 gears and I bought a 21 tooth (the most teeth available from ford)cable gear from the ford garage and that corrected my speed with the 8 tooth output shaft. If you are planning on running lower than 3:73's you need the 7 tooth shaft.I was able to use my FMX flywheel I'm not sure about the c4 flywheel. I fabricated a crossmember after buying one that wouldn't work with my hooker headers.If you need any more inco contact I'd be glad to help.
