Ok I reread the post.
A55 on a a35 frame need vin to register . well seeing as they just changed the rules there must be a way to create title w/o the original MCO document. Your DOT or a notary has a form in pa it's an m1 form for auto titles to reissue a title for missing documentation or if you homemade your rod to get a title.
Normally you need a state mechanics license to get the form but state it is for a moped w/o a vin with a dated receipt for the frame you can fill it all out you can write in where it requires your mechanic # you put in your state DL# as no inspection is required for mopeds it goes through if not you get 6 moths of ride time on a transferred plate from another you own. Get new plate for transferred one. You can speak it 2x even if they don't approve of it...
