Screw sizes, console

[Leon <4thought@bellsouth.net>]

I'm restoring my radio console and other items on the middle hump. Most 
of the really small screws had been replaced by a few metal screws. I 
would like to replace them with the proper machine screws.

The radio console seems to me to be held together with screw size #4-36. 
Which is a very difficult screw to find.

Two questions: Am I correct that the screws are 4-36? And if so, does 
anyone know of a source for these screws?

Thanks for any help
