Fisher-Price motors with kit different from those on andy mark
 

we have ordered 2 replacement fisher-price motors off andy mark to replace one that we broke the connector tab off, only to find that the pinion count was different from those included in the 09' kit. is there a place/way we can get a replacement fisher price KOP motor?

motors in the kit - 16 tooth pinion
ordered motor - 19 tooth pinion

Thanks
Matt
