I've never seen the lug move on a 71-74 Commando (I'm sure some have), but I've been involved with three MK3s that the lug bent upward by collapsing the frame tube. In each case the extended part that is welded to the crossmember broke loose and they appeared to only be tacked. I assumed it was from sitting on the bike on the side stand - in each case the owner said that they never kick started the bike. In one case, I changed the frame and in two, just had a new lug installed with weld to fill the depression in the frame tube and the lug well welded to the frame (the welder's recommendation). Had to provide the welder with a bare good frame for an example to put the new lug on at the right angle and they were bare frame rebuilds.
