I don't see that MGL listed in Motors, Chilton or Hollander as used on a car. All Autolites listed for vehicles are in the I series. Your unit and the attachment does appear to be similar to that shown in the 48-54 parts manual so between Guschas drawing and what the parts plate shows for pieces, perhaps you can get an idea of the hookup. Note the sequence in his drawing.
From your pict dist 1, if the brown item under screw head is a washer, I don't believe it is in the right place. It looks as if the arm from advance is not riding on the screw shoulder directly under the head so it can be free to move and pivot but rather a washer is there instead. Also, that square piece with the double tabs looks turned 90 degrees, and per Guschas drawing not in the proper sequence. I think it needs to be between the arm from vacuum diaphragm and the slot on distributor to keep the arm level. Do you have the smaller square threaded piece with a single tab to provide the threads or nut for the screw? If not and the double tab piece has the threads, you may be missing a bushing to provide some spacing for the movement for the arm as well as a washer and nut under all to lock the tabbed piece solidly to the slotted piece.
