I have a NOS never used before Dyna III D31-3 electronic ignition system kit (For GL1000), with instructions.

But, I have a 1976 CB550K  motorcycle. Anyone wanna trade? Or make me an offer, but I rather trade for one I can use on my CB550.

 The boxes are interchangable just like Dyna 2000 ECU's.

FYI: If you go with the Dyna-S system for your 1976 CB550K. It will be the DS1-2 model. Thats the version I bought for my 1978 CB550K3. Thought it might save you some time looking up the model number...
