Planning on ordering a stock from Numrich but, they list two different stocks for short action LH. Both have exactly the same description.

I'm guessing one is 4.27" spacing and the other is 4.40" spacing (I need a 4.27") but....which one is which ?? I've been trying to contact Numrich for two weeks about it, no responce.

Anyone have any insight ??
