Funny thing - I have a Mallory ZB 248BX (early Caddy dual point dizzy), which has the 24205 points in it now, and Mallory tech just gave me points numbers 24875B (regular) and 24875BX (performance), and condenser number 400. My local warehouse stocks all 3 numbers. Still hunting for the correct cap, rotor, and wires. I'll post back with results No dice, the 24875 does not fit. And FYI, Belmont has rotors, but nothing else :-(
