All the MTX trannys are the same. In the beginning (insert kettle drum/2001 a space odyssey sound) Ford put an undersized clutch in the car. There was a recall and at this point I think you would be hard pressed to find a tranny with the original undersized clutch still in it and working. If you do happen to have the original undersized clutch and flywheel, I would just buy a fidanza (9 pound) off of ebay for about 300 shipped and a stock replacement clutch (they are all the same size) from one of the sho vendors. In addition, since you are new to this board I would do a search about diff pins so you don't have to learn the hard way.
