My apologies. I forgot to add "loop" after the DS. I was talking about the top section of the DS loop (what I'm calling the yoke in this instance).
ah, i see. the connection between the upper to lower is slotted, but uses 8 serrated flange bolts with serrated flange nuts. the slot is for fine tuning the height of the box to prevent contact with the body. it doesn't have enough downward adjustment to contact the driveshaft.
does that answer your question?
