Source for Savage stock cross bolts?

I have a stock that was originally made for the Safari series rifle. Those stocks had crossbolts, but I bought this stock without the crossbolts in it. So, the stock currently has just two holes where the bolts should be. I called Savage to see if they had any extras around and they said they do not. So I'm looking for a source for cross bolts to fit this stock. The cross bolts sold by Midway and Brownells have heads that are too small. Does anyone know where I can get a set that would fit this stock?
