Nope Jerry, you are right.
You cannot just pop the Simplex retros off the band and mount them on Campy shifter bosses (not certain about the thread part, but you definitely can't just swap them over). There are a number of parts that are different between the clamp-on and braze-on versions...

I believe the problem was that the thread on the brazeon bosses it not the same as on the clampons. That is, the posts integrated into the old Simplex clamps are threaded different than Campy-compatible brazeon bosses. Thus, if you want to convert brazeon to clampon or vice versa, you have to find fixng bolts with the correct thread. I've usually been able to use stainless steel socket head bolts from better hardware stores. Now it's possible some of the older brazeon versions are for Simplex brazeons with the same thread a Simplex clamps, I just haven't run into this yet.
