What I found is that a Simplex bolt would not go though the bushing on a Zeus pulley, but a Campy bolt would. I suppose it would work the other way around, except a Simplex bushing would be a little loose on a Campy bolt. I'm talking early 70's stuff here, maybe later Simplex stuff had Campy dimensions.

Good work you got going there except I have put Simplex and Suntour in to
Campy for years. I do not think having a proper fit with the busing to bolt
to really matter in real word riding but that is just my opinion. Happy New
