I will try to get a picture of the clip on the fork end. I am undecided if I will use the NOS boot or reuse the original one on my car. I am leaning toward using the original and saving the NOS for a backup.
A replacement can be made from a piece of pig skin or leather. It looks like you have the rectangle wire with the fingers to hold it to the bell housing, that is good! The clip that holds the material to the fork, if lost, could be fabricated too. Pics of the leather one I made, however, I had the wire frame and fork clip.
Thanks for the pictures Jim. He has an NOS one now also. I was able to get two of them from my Hawaii friend and one went to Oaklyss. For sure need to save the old one so someone can make a replacement in the future with it.
