HELP!!!! No Title

[Layrokr]

It's a long story but here are the cliff notes. Have a project truck I finally have gotten back to. Bought a parts truck with no title and swapped the cabs to project truck and through miss communication with my son old cab and vin tag (which matched my title) went to the scap yard and was chewed up. Now I have no matching title to the project truck. I live in Wa. state and they normally don't check the vin. and titles but Iam concerned if I wanted to sell the truck in the future. I would just file for a lost title but the guy I bought current cab from I can no longer get ahold of. Any ideas anyone. thanks, John
