There have only been two shift lever with linkage that Honda has used on the Goldwings. For all I know they may even be similar enough that they will interchange. There are folks on this forum who would know the answer to this question for sure.

I'd search eBay. Prices tend to be all over the map. If you have the time, they can pop up now and then for ~ $15 including shipping. But you need to be patient.
I wanted to keep my original linkage when I used the DHS Shifter modification. Which is how I came to be shopping for this piece. I've had the DHS Shifter modification now for probably 30,000 miles without any issues. I'd highly recommend it. I've attached a pdf file that covers how I installed mine.
