Never heard of a "quiet title" but that stinks that they pulled your vin tag because the frame has been swapped. I had to drive my clunker to the tag office because it was an out of state sale and a "title 42" maybe that is similar?? They just looked at the vin plate on the door jamb and the mileage on my gauge cluster which was not installed. I had to show them where the Vin plate was
.. They dont bother with frame Vin just the cab/body Vin in Oklahoma. I hope you get this sorted out and get to enjoy the truck. I really wish all 50 states would get on the same page with title work on thses old trucks, and with all the silly business perhaps maybe a required Vin inspection prior to selling so this crap doesn't happen. Must be a green conspiracy to melt down our classics and turn them into Prius-es.
