I may have a 64-40 at home in the older 26.4mm. I think they are 40's. I can check to see if you are interested. I was planning to post them on here in the B&S section soon, along with a bunch of other early 90's components.

The bike looks great with the tape as shown. With a paint job like that, I feel like you can easily go large with color and get away with it.
