Get yourself and everyone else that was in the car at the time checked out to be sure there are no injuries that have not yet shown up.
Go through your insurance, and ask them what the buy back will be. They will give you a number, and then you get to decide if the value of the parts is worth the buy back. Once you buy it back, its pretty much up to you what you do with the car. I suspect the buy back on a 68 Charger with a good front clip wont be cheap. Gene
