[Daylite]

I have a Sea Ray Express Cruiser. I am need of the main cabin door lock. I have repaired it several times but it has finally borken beyhond repai. The original lock was made by Eberhard. They stopped making the locks 15 years ago and ran out of stock 10 years ago. I have also checked with flounder pounder and Sea Ray and cannot find a new or used one. Any help would be greatly appreciated in trying to locate one.
