Bolt Size for SR Oil Pickup Bracket?

[Tyler_240]

I got an SR from a third party who was unable to give me info on what the previous owner had done, etc...I've made a few other posts regarding random shit broken or missing...

I was inspecting/re-sealing the oil pans/baffle/pickup tube. After removing the bolts for the pick-up tube, it almost fell in my face...

The bracket bolt is missing....does anyone know what size it is?

Thanks in advance.
