Three pairs of 1970s vintage Harley-Davidson mirrors. These came from Dixie Distributing when they went out of business. As you can see on the box it is marked 655B. We found them in an old catalog without the 'B'. Not sure what the 'B'  stands for. As you can see in one of the pictures these replace Harley-Davidson number 91875-70. Generally speaking, the numbers after the dash signify the first year that that part comes out. These are new but I've been sitting in a warehouse for decades so expect a little bit of tarnish and for you to clean them up a bit using steel wool for some minor rust spots. The glass surface has some specks also. These are made to be used for left or right. It's just a matter of flipping the mirror over for the other side. You do that by loosening the allen bolt on the back of the mirror
