thanks for the reply im going to see if I can find one then

The remanufactured units don't work too bad - when you can get one. Shop around a bit. You'll also need a distributor cap and rotor to match the later style unit. when available, we usually ask for the equivalent of a '63 F-100 292 truck application. CARDONE #30-2808 will do the trick - it has the later mechanical advance and a single vacuum pot.
