I may not agree with what you have to say, but I'll defend to the death your right to say it.

Find the 1977 on DT250 / 400 and you'll get the full lighting coil with similar plugs to go straight into your two power supply  plugs. 1977 /1978 IT 250 /400  systems work also but you only get a single wire power supply (about 20-25W). Still works for lights but no battery charge circuit. I think you can fit the DT lighting coil in the IT but not sure about the width of the rotor. Backing plates are all the same for DT/IT/YZ 1977/78. Rotor for YZ is narrower (lighter) than the DT but not sure about IT ones.
You'll also need the cdi unit. (YZ/DT/IT will all work just make sure the wires are still in good condition at the base of the CDI box.) Everything is pretty straight forward to plug and play.

I run a 1978 or 79 DT250 flywheel and YZ400 cdi on my RT1 race bike. I'm about to start restoring a DT1-F which will run a DT250 ignition also. RT1 has great spark and no kick back (yet!)
Good luck finding one out there, we are all chasing them for our current or next projects.

you must get an ignition with an outside flywheel.
