Tubb T7 Trigger Torx Size??

[Kimber.204]

I picked up a used Tubb T7T trigger last fall and I just pinned it up to my Bighorn TL3.
I need to adjust the trigger shoe forward to accommodate my gangly digits....problem is that I don't have a Torx Bit small enough for the trigger shoe and I can't find any documentation of what size it is. I looked at the videos online and the pdf of the instructions that I found as well.
Can anyone help me out here maybe @DTubb ?

By the way David, it's a great feeling trigger. I've got a CG Xtreme on my Eliseo Tube Gun and several Timney Calvin Elite two stage triggers on other guns....At this point I like the T7T the best.

Regards,
Ross

Just did a trial and error on mine; T8 felt like the winner.
