They should fit your holders just fine. If you can find the Campi brake blocks from about '91 to '95ish before everything went lowprofile they would fit too.
It doesn't look as nice, or atleast I don't take the time to make them look nice, but the Campi style KoolStops will work too.
I agree those Sintered pads were a diaster!
nice lookig brakes.
