355 Steering Rack bolt sizes

Just wondering if anyone knows what the size of the allen bolt heads are on the 355 steering rack. There are 2 that hold a little plate on to the side of the rack near the spool valve area. There seems to be a tiny bit of fluid seeping from that plate, but I cannot get at it by removing the rubber filler from inside the car. If I knew the exact size, I could bend an allen wrench and possibly get at it from underneath the car and see if I can tighten them. It is just a slight seep that I've been keeping my eye on, and it never seems to develop into a leak. I also do not feel its worth it to remove the rack for this considering the amount of seeping it has at this time. Any help would be greatly appreciated!

 

Hey Thanks! That is exactly what I needed.
