Without being able to source the info, I believe it was a 2-56 x 1/2" Oval Head Machine Screw. Someone else can correct me.
Danny, I might have an extra, if i do its all yours.
Ill check tonight when I get home, if I don't have one I think speedracersX is right about the size
thank you guys! is that a metric thread? tom if you have a extra that would be great!
