Sounds like you've got a large pattern torque converter. They require a 14"/168-tooth flexplate. If you put such a torque plate on, you'll need to change the starter as well.
Tell us more about your combination. You're going to have to drop the transmission one way or the other, but it might make more sense to get a different torque converter, rather than a different flexplate.
