When I was thinking about doing this swap, it was very very hard to find stuff about it so I hope this helps someone...
Just in case any of you with the 200ci I6 were thinking about doing a t5 swap, DO IT!
I just finished my swap with a 1993 World class t5 from ford racing, with an MGW Short throw shifter with race handle and comfort handle.
BY FAR THE BEST THING IVE DONE FOR MY CAR SO FAR!
Here are some tips on making it and easier swap
Get the Bellhousing number so you can get a bellhousing specific adapter kit. (I went by the looks of it cause you cant see the number with the tranny still on) I had the C6OA-6394-C

Once you found your bellhousing, get the adapter kit and it will ask for what bell # you have!

Find a nice T5. I prefer a 93 world class because you are getting better internals with the bugs worked out of it. I bought my transmission brand new, I was kinda iffy on the used from craigslist, just do whatever you feel comfortable with! MAKE SURE YOU GET A WORLD CLASS! If you are spending the money, spend a little more to do it right.

Get a shifter (if you dont want the stock one, which I did NOT)
(if you do not have long arms like I do , I would not get a short throw unless you get mgw with comfort handle)
Get a shifter ball! Read to make sure you get the correct threading for the shifter/shifterball combo since they change.

Get a New clutch,pressure plate, throw out bearing, pilot bearing kit! Really just upgrade since you will be there already. Anything will work. Make sure you know if you need the 8.5" or 9" clutch kit. find your bellhousing first, and it will be easier
Resurface your flywheel! If the teeth are bad, you can get a new ring gear for it! It is way too expensive to replace and find a new flywheel. O'reilly auto parts had them cheap and got them next day! (MAKE SURE YOU KNOW HOW MANY TEETH AND THE DIAMATER OF YOURS!)

Once you buy the adapter kit for your car, it has a new slip yoke with it, take the driveshaft, get the yoke put on, get NEW joints, and have them rebalance it. I DO NOT CARE IF YOU HAD IT BALANCED THE DAY BEFORE, REDO IT WITH THE NEW YOKE.
If you get a world class, you need Dex/Merc Transmission fluid. 2.8 quarts is what mine takes, it was 20 bucks for a 4 quart. You will spill some most likely, so getting a little extra is not bad.
That really sums up the swap, the only things we had to do, were take the e-brake off, get a box of gloves, spray off the underside of the car, back of engine block, and all oily parts with brake cleaner, bought lunch for my friends who helped, and all in all I spent roughly $2560.00 plus a few tools. It is rather expensive, but It works with the inline 6 AND up to 300hp/tq v8, so in the long run it was worth it to me.
CONS OF SWAP: 1)Clutch adjustment bolt was too short so we had to buy a bolt from home depot and modify it, 2) shifter was a bit off center SLIGHTLY so we had to shave a bit to make it fit, 3) waiting for parts that you cant get on the weekend, 4) crossmember and transmission mount had to be modified to fit (holes were off about 1/4 inch, and mount made transmission sit high so we shaved it down), 5) flywheel was difficult to get figured out with ring gear because oreilly's did not have the ring gear listed for the mustang it was for other fords, 6) needed other people, to help.
All-in-all I am super stoked about this swap, I hope I help someone in the future with what they need, if you have any questions, I would love to answer them if I see them. I am 19, 2 jobs, in college, and still learning cars, so I do not have all the answers or expierence, but I hope I shed some light on a subject I had trouble finding info on!
