What are you going to do with a junk crewcab title? It won't match the tag on the dash of your truck. Swapping tags is totally illegal. You don't even know, the truck you bought on ebay may be hot. Or some guy in a divorce is looking for his truck that his wife sold without the title. Or a bank is looking for it, they have a lean on it and whoever had it sold it without the title and skipped town leaving the bank holding the bag and looking for the truck. There are so many things that can go wrong getting a vehicle without a good title, don't ask me how I know.
The truck you have now without a title needs to be researched if you ever want to do anything with it besides part it out. You may lose it, but you can go to the state were you bought it, and the DMV can research the title and see who owns it. They can send a registered letter to them, and they have so many days to respond back. If they never respond, sometimes they will then assign the truck to you(with all the fees of course).
Another way that helps everything go smoother is if you have a buddy that has a garage as his business. He can go and put a mechanics lean on the vehicle. The DMV goes through the same process and if the guy with the title refuses to pay the "repair fees" that are needed, the DMV will assign the title to him so he can sell it and recoup his money.
There may be several other ways to do it, but swapping metal tags is not one of them I would recommend.
