you dont have to smog any pre75 vehicle, regardless of how long it has been sitting, what the title is, or if you lost the title, after 5 years, you have to have a cHP inspection, which is, vin's, seatbelts and lights. or the DMV might just do a vin check. you CAN trailer it and use a tow dolly, but you can't use a tow bar.
(And if your feeling really lucky, when a cop pulls you over for no registration, you should be able to BS them, to get off with a stern warning and maybe some hassling.)
