Hopefully, you have a better experience than I've had with mine.
I changed my Dart Sport from an automatic to a four speed this winter. It has been one big headache from the beginning.
I finally thought it was done a couple of weeks ago but began having a problem with the clutch not disengaging.
So, today when I was under the car I pulled the inspection cover off the bellhousing and found the source of the problem; the pressure plate is defective.
It's a Hayes street/strip unit and was brand new. One of the three fingers (it's a B&B) is not coming all the way back to the throw out bearing. There is about 5/8" of space. The other two fingers are about 1/16" from the t/o bearing. Unfortunately, the pressure plate is about a month past the 90 day warranty, but Summit gave me a great deal on another setup.
My one piece of advice is to gather all the parts needed before the swap, then tackle it all at once. That way your car won't be off the road as long as if you were to buy a piece here and there and put them on as you get them.
