Need screws for 703 control

[LarryMc]

I purchased a used 703 control box on eBay and when it arrived I found that the two small screws that hold the back plate on are both missing. Anyone know if they are available or what size would replace them?

I did an internet search, but couldn't find anything. Any help will be appreciated.
