I need to know what type of flex plate you have in the ruck. Its either the heavy cast iron three piece or the stamped steel plate with the ring gear welded to it. I don't have any of the stamped steel welded ring gear wheels. Any good trans shop will have those or call Brian at BTS for his very good one. I'm using his because the converter he installs on the trans wont fit the older cast iron plates. Also if you have this stamped steel flex plate be careful with the crank spacer. Only BTS is fabricating them because ford no longer supplies them. They are a required spacer when switching from the heavy to stamped flex plates. They look just like part of the rear crank flange too. Several members have not noticied this and had difficultys installing auto to standard flex plates or flywheels.
