Hello KBH. I have a 1950 fleetwin7.5. The coils are definitely bad. Which coil should I retrofit to the old motor? Do you have any idea of the number on the newer ones.? Thankyou.YES, the wires come separately and are soldered to the coils. Easy, if you know how to solder. But this is not a good place to learn. As you suspect, you can damage the coils if not done properly.
You are indeed fortunate if the coils are still good. That motor has the obsolete 580040 coils that were prone to failure and are $$$ if you can find new ones.
