Losborne

Hey guys, newbie here. I just purchased a 79’ DT 175 that had no papers and no title with it. I’m trying to get it street legal but have no idea how to go about doing that. A lot of people have talked about going through Vermont to get it registered. I would also like to find the VIN if I could but can’t seem to do that after looking the bike over pretty hard. Is there a place it usually is? I have a frame and motor serial number which is 2A7-001###. Can anyone speak to any of this? Thanks!
