Speedometer driven gear - 15 tooth?

I'm about to swap in a set of 3.00 gears into my 76 F150. The calculator says I need a 15 tooth driven gear to use with the 7 tooth drive gear on the output shaft of my trans to correct my speedometer. Looking around on ebay I've seen driven gears from 16 to 21 tooth but no 15. Did Ford make a 15 tooth driven gear for the speedometer in my 76 F150?

Thanks-guess I'll use a 16 tooth and be happy with "close enough".
