pedal arm set screw

I am in the process of installing draft seal kit from Krage and noticed that the clutch pedal is missing the set screw to hold the pedal in place. It was very tight but I did get the pedal out and the kit installed but now the pedal is loose and will fall out if I don't find a replacement.

Is the brake pedal screw the same as the clutch? I have not yet removed the brake screw as it looks like I am going to have to remove the whole arm in order to get a good turn on it. If anyone knows what size screw I can use for a replacement please let me know.

BTW, the draft seal kit is well made and looks like it is going to work well.

Thanks, Chris
