G'Day Matt,
Firstly your best bet for a used radiator would be to join a local chapter of one of the Model A clubs & one of the members might be able to help you out, or contact someone like Snyder's or Mike's A ford-able spares for a new one. As far as your spark problem goes, you could try the following. If you're brave enough hold onto the H.T. lead from the coil whilst turning the engine with the ignition on & if you get a slight shock but no spark then the condensor is definitely the culprit.(A bit radical but it works).If there's nothing at all from the H.T. lead, then with the points in the open position (or a piece of paper between the contacts) check for current with a test light or multi-meter between the points arm & a clean ground on the engine. If there's no current then check the distributor side coil pole for current, if yes then there's an open circuit problem between the coil, ignition switch & distributor. If nothen check the battery side of the coil. If you have current there then disconnect the distributor side wire & check that pole again,(obviously if you have no current on the battery side of the coil that's your problem) if you now have current on the distributor side of the coil the wire between the coil/ignition-switch/distributor has gone to ground somewhere along the line. If there's no current the coil is faulty.
Hope this is of some help to you.

DJ.
