Need set trigger screw for Lyman GP rifle

[omgb]

Yesterday the set trigger adjustment screw fell out of my GP rifle while at the range. Before I call Lyman on Monday and deal with their spotty CS dept, do any of you either have an extra screw or, know what size it was so that I can try and find one.

I received a new trigger assembly from Track of the Wolf today. It slipped right in and set me back a wopping $12.99. This is good. Now the bad, the original lost a screw due to a breakage of the internal fly :( However, the new assembly fixes that :) But, the new trigger assembly is no where near as slick and creep free as the old :( i suspect that the new assembly is "lawyered" up some. My rifle is maybe 15 years old. So that got me to thinking..... have any of you sampled a newer GP rifle and compared it to an older one with regards to the trigger? If so, have you noticed the same thing I have?
