With help from the Apollo crew, Betsy and I removed the ETMy QUAD lower structure from BSC10 using the BSC repair arm.  For future reference, the elevator on the repair arm does fit without swinging back the TMS (ACB was already swung back).  The only issue we encountered was that a EQ stop screw at the PenRe had backed itself out a few threads and contacted the removable side plates of the elevator, bending the aluminum EQ stop bracket as we lowered the LS down.  It would probably be best to install these plates after the LS is fully lowered in the future.    

The main chain is currently residing in the welding cleanroom and the reaction chain is in the staging room of the garbing cleanroom.
