When it comes to title issues I'm always surprised by those who advise soliciting advice from the local DMV. That's probably the LAST place you should consult for problem titles! They are bureaucrats whose purpose it is to block anything unusual or non-conforming. Assuming your vehicle is legally-obtained with no theft history and just missing a title due to age (for verification go to https://www.nicb.org/how-we-help/vincheck ) here's some options:
1) If you can locate a title service in your vicinity, use them; they have ways of circumventing the bureaucrats and getting things accomplished.
2) Speak to local towing companies; they routinely place liens on vehicles and, for a fee, can get you a lien title.
3) Get a Vermont registration. On older vehicles Vermont requires a bill of sale only and many owners have successfully taken advantage of this to get a Vermont registration that is then transferable to their state, complete with title. See videos:
