Hi all, new member here looking for advice on my BMW panniers...... Looks as if the inside locking threaded discs that hold the removable bracket on the outside of the pannier has come loose on both aluminium panniers and the brackets have vanished..... does any kind soul know of where I can get these replaced? I did manage to read the parts number from one of them before they disappeared, BMW 7160 7677977 266910 10> PA6-GF15< not sure this helps any. Thanks
