My "winter project" will be radiator, shroud, fans, duct, and ... a whole set of new plug wires. (Two boots have failed so the others can't be far behind. Might as well just replace them all.)
Note to anyone considering doing a similar 3.0L swap: to have the appropriate boots for one set of wires, you will need to buy two sets of wires --
(1) for the distributor end, a set from an appropriate-vintage 6-cylinder AMC/Jeep, and
(2) for the spark plug end, a set from a 3.0L Eagle Premier/Dodge Monaco.
Once the boots are removed, you can make your new wires from whatever source you want - my preference for cable and terminals is MSD.
