Hi folks ! I have just bought a pair of vintage Virago panniers, leather, with 3 straps on back (2 at top, 1 at bottom, all vertical), for my 1992 XV750. Can anyone suggest a decent make of frames/brackets for mounting them on the bike. All I’ve seen so far are either cheap (with 1 mounting point) or stupid money. None have had horizontal bars in the right place. Thanks. Tom Kenny.
