I called the Massachusetts Vehicle Check program on Saturday to find these mysterious EPA/DEP/RMV forms. The rep took down my information, VIN number and said he needed to give this to his supervisor and I would be called back. On Monday I did get a call back and I found out that there are no such forms. All the information about the conversion is listed in the database and all the inspector has to do is input my VIN and under EMISSIONs it will say EXEMPT. So I did all my paper work properly.
I also ordered new headlights and once I get those in I will get the EV inspected. I didn't get anything fancy since most of the aftermarket headlights use HID lamps and I have been told those are not legal in MA. So I just got brand new JDM Crystal Headlights, which are essentially OEM replacements and will use the existing bulbs.
