I'm busy trying to iron out all the little niggles with my project, in doing so I have discovered that the idle screw on the throttle body is completely missing

can’t believe I haven’t noticed this before, just have to add it to the list of many many many odd things I have discovered...
So any suggestions? I obviously need one, currently using an accord type R throttle body do I need to source an idle screw from the same or are there any others that will fit i.e. H22 Prelude ??
Thanks
