Looking for a tail light for a 1977 CB750F Supersport but the ones I've seen so far are unlike this one. They are either mounted by two screws or else 4 screws near the centre. The one I have is mounted by 4 screws very near the corners and it has the following code: STANLEY RR501 SAEA 71 1ATPE181 1 E 11 3246 AU40L1A JAPAN R-169
Any help, better so with part number, would be greatly appreciated. Thanks in advance.
Regards,
Joseph
