Every state rules are not the same on tilting cars with missing titles, been there, done that.
California was a lot harder than Oregon is, I bought a 1966 Dodge Coronet and a 1967 Plymouth Satellite from a local tow yard, both had been their over 20 years, the tow yard owner told the local DMV office here in Oregon that he had lost the titles and gave me a bill of sale and they issue both new titles to me after checking to make sure that cars had not been reported stolen or had liens on them
They are not salvage titles.
