Yep, Crenth I forgot about the metal plates even though the planter I have came with some 16 cell metal corn plates, I've just always used the plastic plates.
It looks like your plates are the 20 cell soy plates, which as a plastic plate I think is called a B-SOY. Either way, the #310992 is all its going take when I go to the co-op and ask for a favor

They'll let me use whatever size I need and if it works out as good for me as it did you, I'll probably go ahead and buy a set.
Thanks a lot Crenth for the pictures and the help, I hope it wasn't to much trouble. And good luck with your plots and that nice buck that's been showing up!!
