Saving a nearly lost car

You've got a bill of sale with the 68 - can't you take that and a rubbing of the vin forom the car and apply for a title in your name? If that's too much hassle, swap it all over to the 75 shell, document it in pictures and let the cousin drive the wheels off the thing. The only time in the futire that it may matter to someone is if/when it is ever sold - and when that time arrives, simply state it is a 75 wearing 68 sheet metal. The E-body crowd willl think nothing of building a 72-74 cuda to wear a 71 grill, tail lights and marker lights, but is still titled as the year that it really is. A buddy of mine has what looks like a 52 MG-TD. However the body plate on the tub and his title are 53. No big deal.
