I've never heard of a 178 tooth flexplate. either 168 or 153 are normal. The 168 tooth is used with the staggered bolt starter, the 153 is used with a straight bolt starter. most automatics use the 168 tooth wheel. my zz4 and the 700r4 in my streetrod use the 168 tooth wheel. so I don't know where the thought came from that it should be 178 I don't think that is correct.
