Wire from Distributor to Coil

My truck had the round coil..But all the plug wires i bought or looked that the wire for the coil was not right..Anybody know where i can get the right one? All the wire sets i have looked at all have the one for the square coil. Any help would be great. I have a 91 B2200

So.......are you meaning that the coil wire, the end that plugs into the coil, does not have the large round rubber cover that fits over the top of the coil and covers the electrical wires & terminals?

If so, most of the aftermarket plug wires won't have that on them........I have seen where owners have cut the large cover off of the stock coil wire and siliconed it onto the new coil wire.

Unless you plan to drive through some deep water, you shouldn't need that rubber cover.......none of mine have it.
