I think I will try to find either a 70-71 E or 67-69 A switch. I am not going to mess with the wires either.
???? It's as simple as removing a terminal front 1st plug & reinserting into the 2nd. Repeat until all are done. Never understood how many are so hesitant to do even some simple wiring tasks on a 12volt system. Now newer cars I can understand, but these older systems are simple in comparison.
Finding a used 72 up switch and plug in may prove just as challenging. Just call up Devinism and he can fix you up with a restored switch that will fit your 70 harness and plug.
