bridge screws

I have a wilkinson bridge that came with a highway one body I bought from ebay. I am getting close to putting this thing together and am ordering a warmoth pro tele neck wednesday. The bridge came without any screws to bolt it to the body.

Anybody know where I can get the screws or know what size they are so I can get them from the Hardware store. The only screws I have found come with a bridge.

thanks in advance

I think some #6 oval head screws 1 inch long should do nicely.
