When the lock broke on my '47 1 ton truck, I looked closer and it was not right. I did some digging and it may have come from a '41 to '48 car driver side. Picture attached of the old, and replacement. The cover would swing up(it swung down on the passenger side of my truck), the shoulder to keep the cover open is correct, in fact the housing and everything is a mirror image. Now, does anybody know if the door latch mechanism from '41 to '48 car would work in our trucks?
