Drew, thanks for your opinion.  The pd came from the manufacturer.  They both have 60 teeth.  One is smaller.  The smaller one rotates the 12 tooth 4.2 times for each Rev.  The larger one rotates the 12tooth 5 times per Rev.  You are welcome to try it.
Both the 12tooth and the larger 60 tooth are correct GT2.
