Matchless G45 rocker cover set. This set of 4 covers I made for my own project seen in the last photo. They were proffessionally cast in magnesium and machined by me to fit straight on to the G45 heads. As I made other spares I won't be needing this set. These covers won't fit G9 or G12 heads.Any questions contact me on 0417590008 or 0395845142.
