Hi All,
While the stand is not correct for the year, these stands were fitted on the first couple of years of the swing arm frame, I believe they were also fitted throughout the life of the "Gold Star" model
In my experience they allow easier use of the centre stand due to the shape of the "feet" allowing a "roll on" action
Secondhand late stands are hard to find and usually well worn !!
I have no experience of pattern late stands quality wise
I dislike the large "leg" on the stands as it tends to dig in on corners
To fit the springs I tie strong wire around the rear rim and tyre, and then forwards to the spring end
rotating the wheel will stretch the spring and it can be then hooked onto the stand
HTH
