The 67 buckets are the same for left and right so I suspect that the 69 will have a left bucket and a right bucket. Basically, a mirror image. Is that the difference?
Backwards and different. The 69 mount ring has 2 mounting brackets for the Eyebrow trim to boot.
The buckets are almost identical so you can swap rings. I had a 68 Bucket grafted on to my 69 fender for repair. Had to change the mount ring due to that.
First pic is a 68 mounting ring the 2nd is the correct 69 mount. Notice the adjusters are located on the opposite side as well.
