"I am looking for some more Arc type their hard to find! "
Yes they are. Or maybe not. If you want new ones.
I had the #29 type arcs custom made. Look for the post on those.
I am confused on the pictures there, one looks like a solid ring of arcs, the other looks like they are spread out with gaps between them on the rotor.
They look longer and narrow on the rotor?
What size are those?
Looks like a great job. Real nice work.
