I purchased a distributor cap for my 63 Healey BJ7, but the wires I got from a different source are loose when I try to push them into the distributor. The cap and wires are the top-loading push-in style and not the side-entry screw-in style. Since I cannot find the proper-fitting wires for this distributor with a Internet search, is there a source I can try to obtain a set of wires from that will fit this distributor, or do I have to order another distributor cap and wires from the same source to get a matched set of wires and a distributor cap? The wires are running more than $40 for a set and I already have 2 sets that don't fit due to being loose.
