This morning Mark, Tyler, Bubba, and I attached the install arm on to the West side of the North door on HAM5. We couldn't find the tub of bolts dedicated to this assembly, but found some others nearby (which included some of the door bolts, that we will need to remember to put back when we are finished). The arm is currently only held on with 3 of the 4 bolts that were previously used with this arm. HEPI blocked access from the front to the lower right thru hole, and there was not enough clearance in the back. Perhaps this arm hasn't been used wiht the new style HEPI's yet? Bubba doesn't think the missing bolt will cause any problems and a possible fix with a shorter piece of all-thread is in the works.

Picture attached of the arm installed but all covered up. (Forgot to take pictures until we were walking away.)
