If I recall, I looked at my dealer for these bolts and a new handle and can only buy complete glass assembly which is obviously not gonna happen.
Now that you have the bolt out it very much resembles something that I used a lot of many years ago while I was building motorcycle engines.
I don’t know whether the dimensions are the same, but if you look up the valve cover bolts for a 1985, 86, 87 Suzuki GSX-R 600, 750 or 1100 engine, they have the exact same style of bolt.
Good luck!
