I'm building a 76 Paramount P10 which I had painted. I bought a new Campy 626/A downtube cable guide and it seems too small. I had to use a much longer than normal bolt to fasten it. An old and rusty example of the same part fits the tube properly with about 1/8" gap at the "ears." Looking thru archived catalog scans, there appears to be only one size of this part. Can someone explain?
