Nothing to worry about, we have a 12V conversion tip that covers what little there is to do. No need to change fuel sender. I recommend an alternator. Wait til you get it and we will answer all electrical questions. Heater motor probably needs swap. Gas gauge may need voltage reducer if still 6V or maybe a reducer. You will just have to do a look around it to see what all it has or does not have. We will get it working with key switch and etc.

Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
